What foreign emissaries came to China to exchange during the Tang Dynasty?

After the Tang Dynasty, China's politics, economy and culture entered a period of comprehensive development, which attracted

foreigners from many neighboring countries to visit and study in China, especially from Central Asia, West Asia, Japan

and countries on the Korean Peninsula. The open foreign policy of the Tang Dynasty was also an important reason for a large number of foreign

nationals to come to China. During the Tang Dynasty, the Emperor of Japan had sent envoys and students

to China more than ten times for exchange and study, and Abe Nakamaru and Jibi Zhenbei were the outstanding

representatives of Japanese students coming to China. They made a longer stay in China, learned a lot of advanced science

culture and technology in China, and brought Chinese Go, tea, art of war, etc. back to their country, which contributed to the development of their own country

. Abe Nakamaru and Choi Chi-won, the founding father of Korean Chinese literature, also formed a deep friendship with many famous Tang Dynasty literati

persons and officials, which has become a good story now celebrated by the people of China, Japan and Korea.
