ABSTRACT
The ancient Sino-Japanese cultural exchange mainly focused on material during the dynasties of Qin and Han, political system in the periods of Sui and Tang, and religious culture during the Song and Yuan dynasties. The Ming Dynasty was founded by Zhu Yuanzhang in Nanjing in 1368 and replaced by the Qing Dynasty in 1644 when Li Zicheng occupied Beijing, which existed in history for about 270 years. Chinese porcelain masters managed to repair the cracks and then returned the teacup to Ashikaga Yoshimasa. Such an experience made the teacup more precious as a relic. The problem of Japanese pirates was a result of special historical conditions, which was closely related with the Japanese political and economic factors. The Japanese had come to present tributes to the Ming Court, but they hurt the Chinese people and looted the property. The diplomats to the Tang Dynasty were appointed by the Japanese emperor while those to the Ming Court by the shogunate.
