According to records, since the Sui Dynasty, Japan has had very close communication with China. In order to learn the culture of the Central Plains, the Japanese sent envoys to China. After the Tang Dynasty, the envoys sent to the Sui Dynasty became envoys sent to the Tang Dynasty. In addition to the name change, the number and batch sent to them have also increased a lot. After studying the culture of the Tang Dynasty, they were often reused after returning to Japan, spreading the culture of the Tang Dynasty to Japan.
In the Tang Dynasty, there was a monk named Jian Zhen. After six trips, he went to Japan to teach Buddhist culture. He not only spread Buddhist theory, but also spread advanced mathematics, medicine and architecture in the Tang Dynasty. He not only brought a large number of books to backward Japan at that time, but also his entourage was proficient in art, medicine and architecture. His arrival has promoted the great progress of Japanese society and culture and become a great symbol of Sino-Japanese friendly exchanges.
From this point of view, the cultures of China and China have great origins, and many Japanese cultures are inherited and innovated on the basis of the original culture in. It is not difficult to find out why there are so many buildings in the streets and alleys of Japan that retain the architectural traces of the Tang Dynasty.
