This article is an attempt to compare the teachings of Confucius and Islam, specifically The Four Books, which are authoritative works on Confucius, and the original sources of Islam, Qur’an and Sunnah. The Four Books are the most quoted sources of Confucius’ thought, namely The Great Learning (Da Xue), The Doctrine of the Mean (Zhong Yong), The Confucian Analects (Lun Yu) and The Works of Mencius (Mengzi). The focus shall be on the concept of family and filial piety as found in Confucianism and Qur’an and Sunnah. Both the teachings of Confucius and Islam emphasise the importance of virtues, ties and order in the family system, for example, the husband is the head of the family and responsible for the family’s existence and security. Islam and Confucianism are both patriarchal, and the husband and men are protectors of the family and deserve much respect. Young members of the family must respect and obey the elders and vice versa. To Confucius, these virtues are the heavenly way and must be

Abstract The Provirus Integration sites for Moloney murine leukemia virus (Pim) kinase family has been studied extensively in tumorigenesis. We previously reported a key role of Pim2 in negatively regulating T-cell responses to alloantigen. We further investigated how Pim2 regulates T-cell mediated anti-tumor responses using murine models of adoptive cell therapy (ACT) and autologous hematopoietic cell transplantation (HCT). We found that Pim2 −/−Pmel CD8 T cells showed enhanced ability for controlling B16 melanoma growth following ACT. Pim2 −/−T cells were more potent to control C1498 leukemia growth after syngeneic HCT. Mechanistically, Pim2 −/−CD8 T cells exhibited increased effector cytokine production, metabolic activities, and unexpectedly CD62L expression than WT controls following activation. Activated Pim2 −/−CD8 T cells had less apoptosis and exhaustion during expansion in IL-2. In vivo, Pim2 −/−CD8 T cells differentiated more into effector, but less into exhausted or suppressive subsets in tumors. On the other hand, Pim2 −/−CD8 T cells exhibited increased longevity in spleen and tumor draining lymph nodes. Our data indicates that Pim2 negatively regulates CD8 T-cell anti-tumor activity by controlling their persistence in secondary lymphoid organs and effector function in tumors. Blocking Pim2 with a Pim2-specific inhibitor improved graft-versus-leukemia activity after autologous HCT and enhanced anti-melanoma effects after ACT. Pim2 inhibition also increased anti-tumor activity of human melanoma-specific T cells and CD19 CAR-T cells. Taken together, targeting Pim2 may serve as a novel strategy for improving cancer immunotherapy through enhancing differentiation and persistence of effector T cells.

There are no completely grammatical studies in Chinese scholarly tradition prior to 1898. Mainly commentary orientation of linguistic works and the general tendency towards the lexicographic form of presentation of philological researches determined function words’ dictionaries to be the leading way of describing linguistic phenomena in the field of grammar. Turning to treatises of this kind contributes to the study of linguistic traditions’ generation and grammatical researches’ formation in China. Special attention is paid to the description of grammatical meanings’ development from lexical one’s and to method of exegesis based on such description, used in《助字辨略》 «Zhu Zi Bian Lüe» (1711) by 刘淇 LiuQi. The structure of the dictionary entries of this work was analyzed, as well as the interpretations in which LiuQi refers to the significant meanings of the described units. Examples of dictionary entries are given, or excerpts from them, provided with translations into Russian. The analysis of the material showed that dictionary entries can vary significantly in length, their internal structure is also not the same, however, in general, it includes an explanation of the meaning of the described unit (from authoritative sources such as 《尔雅》 «Erya», 《广韵》 «Guangyun» and/or a comment made by the author of «Zhu Zi Bian Lüe») and illustrative material from classical works (such as 《论语》 «Lun yu», 《大学》 «Da xue», 《中庸》 «Zhong yong», 《孟子》 «Mencius», 《诗经》 «Shi jing», 《汉书》 «Han shu», etc.). In a number of dictionary entries, LiuQi demonstrates the mechanism of grammatical meanings’ development from the significant one, emphasizing that the grammatical meaning is determined by the significant meaning and is closely connected with it.

The article is devoted to a comprehensive analysis of the main sources, works that developed and supplemented the main elements of Confucian doctrine that appeared during the lifetime of Confucius. The main data on the life and work of thinkers who developed and supplemented the teachings of the Great Teacher of antiquity, the main options for translating and interpreting the names of treatises and basic terminology are outlined. It outlines the main provisions and ideas of the treatise "Zhong Yun" written by Confucius 'direct students, which is of fundamental importance for the process of historical evolution of Confucian doctrine, and clarifies, details and deepens the theses of Confucius' main book "Lun Yu". Against the background of the basic traditional Chinese picture, one of the key principles of Confucianism is pointed out – the principle of the "golden mean", the critical importance of personal virtue of rulers, and the main approaches to determining the formula of human nature. It is determined that the subject of interest "Zhong Yun", broader than the basic treatise "Lun Yu" and denotes cosmogonic and moral properties of the spirit, more richly interprets the inner content of the fundamental category of humanity ("Ren") constructs an integral system of categories, the sources of which are in the depths of ancient Chinese mythology. The main concepts and meanings of the work "Da Xue" ("great teaching") are established, one of the most fundamental traditional categories of which is the concept of "where" – personal "grace", "achievement, acquisition", and the uniqueness and special place of a person in the universe is the ability to follow "due justice". The quintessence of the DA Xue worldview system is the presumption of immanent virtue of human nature, which should radiate from those in power in the form of "humanity"; the basic thesis of the treatise is the attitude according to which the ruler who "does not show" virtue is deprived of his right to rule. It is stated that the work named after the outstanding thinker of traditional China, Meng Tzu, was of fundamental importance for the long evolution of Confucianism. (Meng Ke), who not only expanded the leading principles of Confucius, but also improved the teachings of the great teacher by actualizing and considering new issues. This approach transformed the teachings of Kun Tzu into a harmonious construction of judgments, which later turned into the official government ideology and worldview system of the Great Chinese society, which has existed for thousands of years. It is to Meng Tzu that the orientation to consider human nature moral goes back, one of his most original ideas is the concept of the heart-mind, which is provided on the one hand by an innate, intuitive ability, moral instinct, and on the other by benevolence. On the contrary, the approaches of another thinker, Sun Tzu, were completely antagonistic to Meng Tzu's ideas and proved the conclusion that human nature is evil. Sun Tzu's concept is located exactly on the border between Confucianism and legalism, but the Thinker (unlike the legists) believed that it was not punishments and rewards that should curb the evil nature of a person, but moral improvement and high literature, that is, culture. Sun Tzu was the first in Confucianism and proved the concept of an enlightened monarchy based on the principle of both traditional morality and the authority and power of the law. Against the background of the study of significant monographic literature, conclusions are drawn about the almost instantaneous beginning of the complex deepening, improvement and development of teaching, already by the first students of Confucius. Confucianism was formed as a method of interpreting the ancient Chinese system of symbols and concepts, categories laid down in mythological form in an active, active spirit. The development of Confucian doctrine was due to the incorporation of elements of other teachings. Confucianism essentially developed through finding common ground with other Chinese doctrines. The key idea that emerged in the development of Confucianism is the statement that everything in a person, including his inner world, is just a reflection of the natural world, and the restoration of perfect social institutions will not mechanically restore perfect order in the Middle Kingdom. The core of the DA Xue ideological system is the assumption of the inner virtue (de) of human nature, which must be shown by those in power. In the course of its long evolution, Confucian traditional thought put certain fundamental problems and categories on the agenda much earlier than European thinkers did, of course, at the ancient, traditional level synchronous with that distant century

Abstract Background: Fibroblast growth factors (FGFs) and their receptors (FGFRs) regulate numerous cellular processes. Dysregulation of FGFR signaling due to receptor fusion, mutation or amplification is observed across multiple cancer types, making activated FGFRs an important therapeutic target. Herein, we present the preclinical characterization of HMPL-453, a highly potent and selective inhibitor of FGFR1, 2, and 3, discovered and being currently developed in phase II clinical trial (NCT04353375) by HUTCHMED. Methods: Kinase activity was measured by Transcreener™ Fluorescence Polarization assay or Z’-LYTE kinase assay. In vitro anti-proliferation activity was measured by CellTiter-Glo luminescent or CCK-8 assay. The effect of HMPL-453 on FGFR signaling pathway was detected by western blot. Multiple tumor models with FGFR alteration were applied in Nu/Nu nude mice to determine anti-tumor efficacy of 453 as a single agent. A model in immune-competent BALB/c mice inoculated with the constructed NIH/3T3 cells carrying FGFR2-AHCYL1 fusion was chosen to investigate the combination effect of HMPL-453 with anti-PD-1 antibody. Results: HMPL-453 potently inhibited the tyrosine kinase activities of recombinant FGFR 1, 2, and 3 in vitro (IC50 values of 6, 4, and 6 nM, respectively) with weaker activity against FGFR4 (IC50 = 425 nM). HMPL-453 selectively inhibited proliferation of tumor cell lines with dysregulated FGFR signaling (GI50s: 3~105 nM) compared with cell lines lacking FGFR aberrations (GI50s > 1.5 µM). HMPL-453 demonstrated strong inhibition of phosphorylation of FGFR and downstream protein in tumor cell lines harboring FGFR2 fusion. Oral administration of HMPL-453 could induce time- and dose-dependent inhibition of phosphorylation of FGFR and resulted in remarkable and dose-dependent anti-tumor activity in multiple FGFR-altered tumor models. HMPL-453 at the dose of 50 mg/kg/day could induce tumor regression in most tumor models tested. Moreover, HMPL-453 significantly improved anti-tumor activity of anti-PD-1 antibody in a FGFR2 fusion model by priming the immune environment. Conclusion: HMPL-453 is a highly potent and selective inhibitor of FGFR 1, 2, and 3 with strong activity against FGFR-deregulated tumors in preclinical models, supporting continued investigation in patients with FGFR alterations (such as fusion and mutation) either as a single agent or in combination with PD-1 blockade.

Abstract In pancreatic ductal adenocarcinoma (PDAC), cancer associated fibroblasts (CAFs) play critical and complex roles in the tumor microenvironment. CAFs are also a major cell type in the desmoplastic stroma in PDAC and may account for half of the entire tumor tissue. Multiple subtypes of CAFs have been suggested, but the tissue origin(s) of CAF subtypes are unknown and genetic tools to robustly target them in vivo are lacking. Here we aimed to examine three potential tissue sources of CAFs: the pancreatic epithelium (through epithelium-to-mesenchyme transition), the bone marrow (through circulation), and the pancreatic mesenchyme or tissue resident fibroblasts (TRFs) in the normal pancreas (through proliferation). We utilized a genetically engineered mouse model of PDAC, where Kras and p53 mutations were engineered in the pancreatic epithelium using an Flp-Frt system. To determine whether the pancreatic epithelium gives rise to CAFs, we permanently labeled the pancreatic epithelium with a GFP reporter and traced their cell descendants by GFP expression. Despite robust GFP labeling of the epithelium, GFP expression was rarely identified in CAFs. To determine whether the bone marrow gives rise to CAFs, we transplanted donor bone marrow carrying a ubiquitously expressed GFP reporter to GFP-negative recipient mice. We found that minimal proportion of pancreatic CAFs were tagged with GFP. Lastly, to determine whether pancreatic TRFs give rise to CAFs, we used an inducible CreER-LoxP system to allow for permanent Tomato labeling in TRF progenitors, the splanchnic mesenchyme, during mid-gestation. Lineage tracing in PDAC showed that the vast majority of CAFs were labeled with Tomato expression, suggesting their splanchnic origin. Furthermore, certain splanchnic gene expression signatures persisted in subsets of CAFs in both the PDAC mouse model and human patient samples. Deletion of one of the splanchnic genes, Gata6, in CAFs resulted in increased tumor burden in the pancreas, suggesting a tumor-restraining role of Gata6 in CAFs. In summary, we found that the pancreatic epithelium and bone marrow contributes to a minimal proportion of CAFs in PDAC. Meanwhile, pancreatic TRFs are derived from the splanchnic mesenchyme during fetal development and they expand to contribute to the vast majority of CAFs in PDAC. Moreover, the persistence of splanchnic signature defines subtypes of CAFs, with a potential tumor-suppressing function. This study provides genetic approaches to robustly target CAFs in vivo, and novel insights into CAF origin, heterogeneity and function in PDAC.

Abstract Changes in mitochondrial bioenergetics in aging T-cells play a key role in the decrease in T-cell function and tumor resistance with aging. The bioactive sphingolipid ceramide, induced by aging stress, is a major player in these changes, as its accumulation at the mitochondrial membranes of both mouse and human aging T-cells induces ceramide-dependent mitophagy, which decreases T-cell viability, cytokine secretion, and anti-tumor activity. Using knock-out mouse models and pharmacological inhibition, we show that C14-ceramide accumulation in the mitochondria and mitophagy in the T-cells of aging mice are dependent on Ceramide Synthase 6 (CerS6), an enzyme responsible for C14/C16-ceramide synthesis. Interestingly, sphingosine kinase 2 (SphK2), another enzyme involved in ceramide metabolism inhibits HDAC1/2 function in aging T-cells, epigenetically inducing CerS6 expression and the resultant ceramide-dependent mitophagy, which ultimately decreases T-cell anti-tumor function. Both CerS6-/- and SphK2-/- aging T-cells were protected from the reduction in T-cell function, and their anti-tumor function was maintained in adoptive-cell transfer experiments to mice with melanoma. Besides lipid signaling, other metabolic changes associated with this aging-induced process have not been explored, and the utility of correcting these metabolic changes to restore T-cell function has not been evaluated. We studied the total hydrophilic metabolome of aging T-cells undergoing ceramide-dependent mitophagy to assess the metabolic changes occurring in these cells. Our findings show a general depletion of tricarboxylic acid cycle (TCA) metabolites in aging T-cells, with pools of fumarate, malate, and argininosuccinate significantly decreasing in both mouse and human aging T-cells. Interestingly, these changes were mirrored by similar changes in human cancer cells undergoing ceramide-dependent mitophagy, suggesting that these changes might constitute a general metabolic signature for this specific mitophagy process with deleterious effects on anti-tumor functions of aging T-cells. Both in vitro and in vivo supplementation of fumarate to mouse T-cells seemed to correct some of the functional defects observed in aging, with a protection of T-cell viability, cytokine production, and tumor killing capacity in co-cultures with tumor cells. The fumarate supplementation also led to a decrease in ceramide-dependent mitophagy in the aging T-cells, indicating an interplay between ceramide-dependent mitophagy and fumarate metabolism. Overall, these studies help explain the mechanisms behind aging-related dysregulation of T-cell anti-tumor activity, which can be restored by inhibiting ceramide-dependent mitophagy by pharmacological and genetic tools or by reprogramming fumarate metabolism in aging T cells.

The articles on China and Japan in this special issue deal with modernity and postmodernity as exemplified by modern Chinese writers, such as Yu Dafu (1896–1945) and Fei Ming (1901–1967); contemporary Chinese and Japanese writers, such as Can Xue and Sayaka Murata; and the connections between modern life and antiquarian book collections in Macau. These articles, hailing from the different perspectives provided by history, philosophy, and translation studies, collectively contribute to our understanding of the literary manifestation, reflection, and representation of modernity and postmodernity in twentieth-century China and Japan.

Ethnopharmacology relevance: Yunnan Baiyao (YNBY), a traditional Chinese medicine formulae, has some significant properties including activating blood circulation to dissipate blood stasis (Huo-Xue-Hua-Yu), eliminating swelling and alleviating pain (Xiao-Zhong-Zhi-Tong), and eliminating necrotic tissues and promoting granulation (Qu-Fu-Sheng-Ji).Aim of this study: This paper intends to provide a comprehensive and critical analysis of studies on YNBY, proposing new possible therapeutic directions of this formula.Materials and methods: Relevant data on YNBY were retrieved from available databases and a hand-search by searching the keywords such as “Yunnan Baiyao,” “pharmacology,” “toxicity,” and “clinical applications.”Results: Traditionally, YNBY has been used to cure hemorrhage, bruises, swelling, and pain caused by injuries in the Chinese folk. Modern pharmacological studies show that YNBY possesses pharmacological activities including hemostasis, invigorating the circulation of blood, wound healing, anti-inflammation, analgesia, antibiosis, infection prevention, and other effects. Toxicological studies demonstrate that YNBY has a certain toxicology, which is mainly caused by Aconitum alkaloids from Cao-wu (CW, Aconiti Kusnezoffii Radix). The developmental non-toxic reaction dose (NOAEL) of YNBY for embryos and fetuses is 0.5 g/kg in rats. In addition, the NOAEL for fertility and early embryo development toxicity is 4.0 g/kg in rats. Clinical trials have confirmed the safety of YNBY in a large number of patients, and adverse drug reactions (ADRs) such as abdominal pain, diarrhea, allergy, and others in very few people. YNBY is routinely used in clinic to cure bleeding, pain, swelling, upper digestive tract ulcer, postoperative wound, arthritis, mouth ulcers, ulcerative colitis, etc.Conclusions: Hemostasis is a conspicuous effect of YNBY. Except for this effect, analgesia and anti-infection may be new research directions of this formula. In addition, the in vitro and in vivo pharmacology and mechanisms of action of YNBY are encouraged as well as the pharmacokinetics of this formulae. Furthermore, the material basis of the pharmacological effects of YNBY also needs clear identification.

Graphene-based composites have received a great deal of attention in recent year because the presence of graphene can enhance the conductivity, strength of bulk materials and help create composites with superior qualities. Moreover, the incorporation of metal oxide nanoparticles such as Fe3O4 can improve the catalytic efficiency of composite material. In this work, we have synthesized a composite material with the combination of reduced graphene oxide (rGO), and Fe3O4 modified tissue-paper (mGO-PP) via a simple hydrothermal method, which improved the removal efficiency of the of methylene blue (MB) in water. MB blue is used as the model of contaminant to evaluate the catalytic efficiency of synthesized material by using a Fenton-like reaction. The obtained materials were characterized by SEM, XRD. The removal of materials with methylene blue is investigated by UV-VIS spectroscopy, and the result shows that mGO-PP composite is the potential composite for the color removed which has the removal efficiency reaching 65% in acetate buffer pH = 3 with the optimal time is 7 h. Keywords Graphene-based composite, methylene blue, Fenton-like reaction.

Introdução: A transmissão SARS-CoV-2 de humano para humano pode ocorrer e o risco de propagação no ar durante os procedimentos odontológicos geradores de aerossóis permanece uma preocupação. Acredita-se que um enxaguatório bucal antimicrobiano pré-operacional reduza o número de micróbios orais. No entanto, a eficácia do enxaguatório bucal pré-procedimento na redução do número de microrganismos disseminados por meio do aerossol gerado por procedimentos odontológicos ainda não está clara. Objetivo: avaliar através de uma revisão de literatura o uso de enxaguantes bucais na redução da carga viral do SARS-CoV-2. Materiais e Método: O levantamento literário para esta pesquisa foi realizado no período de dezembro de 2019 a 10 de agosto de 2020 nas bases de dados Scielo e Medline/PubMed. Na estratégia de busca, foram utilizadas as palavras “SARS-CoV-2”, “2019-nCoV”, “COVID-19”, “Dentistry”, “Odontologia”, “Odontología”, “Mouthwashes”, “Antissépticos Bucais” e “Antisépticos Bucales”. Resultados: Uma busca sistematizada foi realizada, foram encontrados 661 artigos, após a realização da leitura criteriosa dos artigos completos foram selecionados 42 artigos. 88% dos estudos indicavam o uso de Peróxido de hidrogênio a 1%, 76% indicavam Povidine 0,2% e apenas 19% o uso da Clorexidina a 0,12%. Conclusão: Os estudos presentes na literatura apresentam divergências nas indicações e porcentagens dos enxaguantes indicados. Os protocolos clínicos devem ser avaliados para reduzir o risco de transmissão e proteger pacientes e profissionais.Descritores: Infecções por Coronavírus; Betacoronavirus; Odontologia; Antissépticos Bucais.ReferênciasGe ZY, Yang LM, Xia JJ, Fu XH, Zhang YZ.

The curtain rose. The howling of desert wind filled the performance hall in the Shanghai Grand Theatre. Into the center stage, where a scenic construction of a mountain cliff and a desert landscape was dimly lit, entered the character of the Daoist priest Wang Yuanlu (1849–1931), performed by Chen Yizong. Dressed in a worn and dusty outfit of dark blue cotton, characteristic of Daoist priests, Wang began to sweep the floor. After a few moments, he discovered a hidden chambre sealed inside one of the rock sanctuaries carved into the cliff.Signaled by the quick, crystalline, stirring wave of sound from the chimes, a melodious Chinese ocarina solo joined in slowly from the background. Astonished by thousands of Buddhist sūtra scrolls, wall paintings, and sculptures he had just accidentally discovered in the caves, Priest Wang set his broom aside and began to examine these treasures. Dawn had not yet arrived, and the desert sky was pitch-black. Priest Wang held his oil lamp high, strode rhythmically in excitement, sat crossed-legged in a meditative pose, and unfolded a scroll. The sound of the ocarina became fuller and richer and the texture of the music more complex, as several other instruments joined in.Below is the opening scene of the award-winning, theatrical dance-drama Dunhuang, My Dreamland, created by China’s state-sponsored Lanzhou Song and Dance Theatre in 2000. Figure 1a: Poster Side A of Dunhuang, My Dreamland Figure 1b: Poster Side B of Dunhuang, My DreamlandThe scene locates the dance-drama in the rock sanctuaries that today are known as the Dunhuang Mogao Caves, housing Buddhist art accumulated over a period of a thousand years, one of the best well-known UNESCO heritages on the Silk Road. Historically a frontier metropolis, Dunhuang was a strategic site along the Silk Road in northwestern China, a crossroads of trade, and a locus for religious, cultural, and intellectual influences since the Han dynasty (206 B.C.E.–220 C.E.). Travellers, especially Buddhist monks from India and central Asia, passing through Dunhuang on their way to Chang’an (present day Xi’an), China’s ancient capital, would stop to meditate in the Mogao Caves and consult manuscripts in the monastery's library. At the same time, Chinese pilgrims would travel by foot from China through central Asia to Pakistan, India, Nepal, Bangladesh, and Sri Lanka, playing a key role in the exchanges between ancient China and the outside world. Travellers from China would stop to acquire provisions at Dunhuang before crossing the Gobi Desert to continue on their long journey abroad. Figure 2: Dunhuang Mogao CavesThis article approaches the idea of “abroad” by examining the present-day imagination of journeys along the Silk Road—specifically, staged performances of the various Silk Road journey-themed dance-dramas sponsored by the Chinese state for enhancing its cultural and foreign policies since the 1970s (Kuang).As ethnomusicologists have demonstrated, musicians, choreographers, and playwrights often utilise historical materials in their performances to construct connections between the past and the present (Bohlman; Herzfeld; Lam; Rees; Shelemay; Tuohy; Wade; Yung: Rawski; Watson). The ancient Silk Road, which linked the Mediterranean coast with central China and beyond, via oasis towns such as Samarkand, has long been associated with the concept of “journeying abroad.” Journeys to distant, foreign lands and encounters of unknown, mysterious cultures along the Silk Road have been documented in historical records, such as A Record of Buddhist Kingdoms (Faxian) and The Great Tang Records on the Western Regions (Xuanzang), and illustrated in classical literature, such as The Travels of Marco Polo (Polo) and the 16th century Chinese novel Journey to the West (Wu). These journeys—coming and going from multiple directions and to different destinations—have inspired contemporary staged performance for audiences around the globe.Home and Abroad: Dunhuang and the Silk RoadDunhuang, My Dreamland (2000), the contemporary dance-drama, staged the journey of a young pilgrim painter travelling from Chang’an to a land of the unfamiliar and beyond borders, in search for the arts that have inspired him. Figure 3: A scene from Dunhuang, My Dreamland showing the young pilgrim painter in the Gobi Desert on the ancient Silk RoadFar from his home, he ended his journey in Dunhuang, historically considered the northwestern periphery of China, well beyond Yangguan and Yumenguan, the bordering passes that separate China and foreign lands. Later scenes in Dunhuang, My Dreamland, portrayed through multiethnic music and dances, the dynamic interactions among merchants, cultural and religious envoys, warriors, and politicians that were making their own journey from abroad to China. The theatrical dance-drama presents a historically inspired, re-imagined vision of both “home” and “abroad” to its audiences as they watch the young painter travel along the Silk Road, across the Gobi Desert, arriving at his own ideal, artistic “homeland”, the Dunhuang Mogao Caves. Since his journey is ultimately a spiritual one, the conceptualisation of travelling “abroad” could also be perceived as “a journey home.”Staged more than four hundred times since it premiered in Beijing in April 2000, Dunhuang, My Dreamland is one of the top ten titles in China’s National Stage Project and one of the most successful theatrical dance-dramas ever produced in China. With revenue of more than thirty million renminbi (RMB), it ranks as the most profitable theatrical dance-drama ever produced in China, with a preproduction cost of six million RMB. The production team receives financial support from China’s Ministry of Culture for its “distinctive ethnic features,” and its “aim to promote traditional Chinese culture,” according to Xu Rong, an official in the Cultural Industry Department of the Ministry. Labeled an outstanding dance-drama of the Chinese nation, it aims to present domestic and international audiences with a vision of China as a historically multifaceted and cosmopolitan nation that has been in close contact with the outside world through the ancient Silk Road. Its production company has been on tour in selected cities throughout China and in countries abroad, including Austria, Spain, and France, literarily making the young pilgrim painter’s “journey along the Silk Road” a new journey abroad, off stage and in reality.Dunhuang, My Dreamland was not the first, nor is it the last, staged performances that portrays the Chinese re-imagination of “journeying abroad” along the ancient Silk Road. It was created as one of many versions of Dunhuang bihua yuewu, a genre of music, dance, and dramatic performances created in the early twentieth century and based primarily on artifacts excavated from the Mogao Caves (Kuang). “The Mogao Caves are the greatest repository of early Chinese art,” states Mimi Gates, who works to increase public awareness of the UNESCO site and raise funds toward its conservation. “Located on the Chinese end of the Silk Road, it also is the place where many cultures of the world intersected with one another, so you have Greek and Roman, Persian and Middle Eastern, Indian and Chinese cultures, all interacting. Given the nature of our world today, it is all very relevant” (Pollack). As an expressive art form, this genre has been thriving since the late 1970s contributing to the global imagination of China’s “Silk Road journeys abroad” long before Dunhuang, My Dreamland achieved its domestic and international fame. For instance, in 2004, The Thousand-Handed and Thousand-Eyed Avalokiteśvara—one of the most representative (and well-known) Dunhuang bihua yuewu programs—was staged as a part of the cultural program during the Paralympic Games in Athens, Greece. This performance, as well as other Dunhuang bihua yuewu dance programs was the perfect embodiment of a foreign religion that arrived in China from abroad and became Sinicized (Kuang). Figure 4: Mural from Dunhuang Mogao Cave No. 45A Brief History of Staging the Silk Road JourneysThe staging of the Silk Road journeys abroad began in the late 1970s. Historically, the Silk Road signifies a multiethnic, cosmopolitan frontier, which underwent incessant conflicts between Chinese sovereigns and nomadic peoples (as well as between other groups), but was strongly imbued with the customs and institutions of central China (Duan, Mair, Shi, Sima). In the twentieth century, when China was no longer an empire, but had become what the early 20th-century reformer Liang Qichao (1873–1929) called “a nation among nations,” the long history of the Silk Road and the colourful, legendary journeys abroad became instrumental in the formation of a modern Chinese nation of unified diversity rooted in an ancient cosmopolitan past. The staged Silk Road theme dance-dramas thus participate in this formation of the Chinese imagination of “nation” and “abroad,” as they aestheticise Chinese history and geography. History and geography—aspects commonly considered constituents of a nation as well as our conceptualisations of “abroad”—are “invariably aestheticized to a certain degree” (Bakhtin 208). Diverse historical and cultural elements from along the Silk Road come together in this performance genre, which can be considered the most representative of various possible stagings of the history and culture of the Silk Road journeys.In 1979, the Chinese state officials in Gansu Province commissioned the benchmark dance-drama Rain of Flowers along the Silk Road, a spectacular theatrical dance-drama praising the pure and noble friendship which existed between the peoples of China and other countries in the Tang dynasty (618-907 C.E.). While its plot also revolves around the Dunhuang Caves and the life of a painter, staged at one of the most critical turning points in modern Chinese history, the work as a whole aims to present the state’s intention of re-establishing diplomatic ties with the outside world after the Cultural Revolution. Unlike Dunhuang, My Dreamland, it presents a nation’s journey abroad and home. To accomplish this goal, Rain of Flowers along the Silk Road introduces the fictional character Yunus, a wealthy Persian merchant who provides the audiences a vision of the historical figure of Peroz III, the last Sassanian prince, who after the Arab conquest of Iran in 651 C.E., found refuge in China. By incorporating scenes of ethnic and folk dances, the drama then stages the journey of painter Zhang’s daughter Yingniang to Persia (present-day Iran) and later, Yunus’s journey abroad to the Tang dynasty imperial court as the Persian Empire’s envoy.Rain of Flowers along the Silk Road, since its debut at Beijing’s Great Hall of the People on the first of October 1979 and shortly after at the Theatre La Scala in Milan, has been staged in more than twenty countries and districts, including France, Italy, Japan, Thailand, Russia, Latvia, Hong Kong, Macao, Taiwan, and recently, in 2013, at the Lincoln Center for the Performing Arts in New York.“The Road”: Staging the Journey TodayWithin the contemporary context of global interdependencies, performing arts have been used as strategic devices for social mobilisation and as a means to represent and perform modern national histories and foreign policies (Davis, Rees, Tian, Tuohy, Wong, David Y. H. Wu). The Silk Road has been chosen as the basis for these state-sponsored, extravagantly produced, and internationally staged contemporary dance programs. In 2008, the welcoming ceremony and artistic presentation at the Olympic Games in Beijing featured twenty apsara dancers and a Dunhuang bihua yuewu dancer with long ribbons, whose body was suspended in mid-air on a rectangular LED extension held by hundreds of performers; on the giant LED screen was a depiction of the ancient Silk Road.In March 2013, Chinese president Xi Jinping introduced the initiatives “Silk Road Economic Belt” and “21st Century Maritime Silk Road” during his journeys abroad in Kazakhstan and Indonesia. These initiatives are now referred to as “One Belt, One Road.” The State Council lists in details the policies and implementation plans for this initiative on its official web page, www.gov.cn. In April 2013, the China Institute in New York launched a yearlong celebration, starting with "Dunhuang: Buddhist Art and the Gateway of the Silk Road" with a re-creation of one of the caves and a selection of artifacts from the site. In March 2015, the National Development and Reform Commission (NDRC), China’s top economic planning agency, released a new action plan outlining key details of the “One Belt, One Road” initiative. Xi Jinping has made the program a centrepiece of both his foreign and domestic economic policies. One of the central economic strategies is to promote cultural industry that could enhance trades along the Silk Road.Encouraged by the “One Belt, One Road” policies, in March 2016, The Silk Princess premiered in Xi’an and was staged at the National Centre for the Performing Arts in Beijing the following July. While Dunhuang, My Dreamland and Rain of Flowers along the Silk Road were inspired by the Buddhist art found in Dunhuang, The Silk Princess, based on a story about a princess bringing silk and silkworm-breeding skills to the western regions of China in the Tang Dynasty (618-907) has a different historical origin. The princess's story was portrayed in a woodblock from the Tang Dynasty discovered by Sir Marc Aurel Stein, a British archaeologist during his expedition to Xinjiang (now Xinjiang Uygur autonomous region) in the early 19th century, and in a temple mural discovered during a 2002 Chinese-Japanese expedition in the Dandanwulike region. Figure 5: Poster of The Silk PrincessIn January 2016, the Shannxi Provincial Song and Dance Troupe staged The Silk Road, a new theatrical dance-drama. Unlike Dunhuang, My Dreamland, the newly staged dance-drama “centers around the ‘road’ and the deepening relationship merchants and travellers developed with it as they traveled along its course,” said Director Yang Wei during an interview with the author. According to her, the show uses seven archetypes—a traveler, a guard, a messenger, and so on—to present the stories that took place along this historic route. Unbounded by specific space or time, each of these archetypes embodies the foreign-travel experience of a different group of individuals, in a manner that may well be related to the social actors of globalised culture and of transnationalism today. Figure 6: Poster of The Silk RoadConclusionAs seen in Rain of Flowers along the Silk Road and Dunhuang, My Dreamland, staging the processes of Silk Road journeys has become a way of connecting the Chinese imagination of “home” with the Chinese imagination of “abroad.” Staging a nation’s heritage abroad on contemporary stages invites a new imagination of homeland, borders, and transnationalism. Once aestheticised through staged performances, such as that of the Dunhuang bihua yuewu, the historical and topological landscape of Dunhuang becomes a performed narrative, embodying the national heritage.The staging of Silk Road journeys continues, and is being developed into various forms, from theatrical dance-drama to digital exhibitions such as the Smithsonian’s Pure Land: Inside the Mogao Grottes at Dunhuang (Stromberg) and the Getty’s Cave Temples of Dunhuang: Buddhist Art on China's Silk Road (Sivak and Hood). They are sociocultural phenomena that emerge through interactions and negotiations among multiple actors and institutions to envision and enact a Chinese imagination of “journeying abroad” from and to the country.ReferencesBakhtin, M.M.
