Actually, there are many reasons for this phenomenon. On the one hand, in fact, in ancient times, the relationship between Japan and China was not as it is now, because the relationship between the two countries was relatively stiff in the hearts of the two peoples during the War of Resistance against Japanese Aggression period, while in ancient China, the relationship between Japan and China was relatively good.

Although many people have been talking about Japan's former enemies or something. However, relevant information shows that the Japanese are not Japanese now, and Japan often came to China to study and communicate in ancient times. Take the Tang Dynasty as an example. At that time, Japan sent many monks to study in the Tang Dynasty, and Japan also learned many advanced cultures from the Tang Dynasty, which promoted the development of Japanese civilization.

It can be said that in ancient times, China was very helpful to Japan. Many people accept that the relationship with Japan is not as difficult as we are now, but in ancient times it can be said that it is just the opposite. On the other hand, it was in the Song Dynasty, when it was very rich. And until now, some people think that the Song Dynasty is actually the richest dynasty in the history of China.

Compared with the Tang Dynasty and the Qing Dynasty, it can be said to be very rich. Therefore, from this perspective, as a large and wealthy Song Dynasty, it is not surprising that many neighboring countries came to worship or study at that time. Among them, Japan can be said to be a fanatical fan.
