Abstract:Sino-Indian Studies (Chindia) initiated by Rabindrananth Tagore and Visiva Bharat is an open-ended topic. Its academic discourse, content and extension have been constantly constructed and enriched. Since 1930s, four great Indologists Prabodh Chandra Bagchi, S. Radhakrishnan, Tan Chung, Lokesh Chandra have composed several volumes of India and China with the approaches of historiography, comparative culture and comparative philosophy, reflecting the development of Sino-Indian studies in the past century. Following the tradition of French Sinology, Prabodh Chandra Bagchi recreated the exchanges between China and India with concrete historical evidence. Lokesh Chandra and his father Raghu Vira, a renowned Sinologist, combined historical researches and travel notes such as personal visits, fieldworks, oral accounts and diaries to prove history with “cultural relics” and recapture the cultural exchange at that time. Raghu Vira’s visit to China in 1955 is a precious memory of the cultural exchanges between China and India in modern times. Tan Chung conducted a comparative study on the original culture and the dynamic influence of culture to explore the cultural genes that may be shared by Chinese and Indian civilizations. From the perspective of religious studies, S. Radhakrishnan made a comparative analysis of the secularity of Confucianism, the transcendence of Taoism and the spirituality of Buddhism, realizing that Chinese thoughts and Indian thoughts both aim at the spiritual transformation of human beings. Chinese thoughts and Indian thoughts may share similarities and fuse with each other. Moreover, the significance of the fusion lies in the reconstruction of values, which is also the fundamental purpose of “Sino-Indian studies” which started from cultural exchanges and aims at the establishment of new civilizations.
