Why did 930,000 Japanese come to China to recognize their ancestors and return to their ancestral home, setting off a "homecoming tide"?

China and Japan face each other across the sea. In the past few thousand years, the two countries have conducted many exchanges and studies. China in its heyday in the Tang Dynasty was a paradise in the East for other countries. A small country like Japan, especially in awe of the Tang Dynasty, often sent people to the Tang Dynasty to learn cultural knowledge, hoping to enhance its comprehensive national strength. Unfortunately, this great country flavor disappeared in the late Qing Dynasty, and eventually became a lamb wantonly invaded by other countries. In this process, Japan became strong rapidly because of timely reforms.

In 1930s, Japan launched a large-scale war of aggression against China, which caused great disasters to our country. Countless Chinese sons and daughters died tragically at the hands of Japanese aggressors, and this national hatred has not been forgotten until now. After the end of War of Resistance against Japanese Aggression, due to historical issues, China and Japan resumed normal exchanges after decades of stalemate. With the passage of time, China and Japan have cooperated in many fields such as economy and technology. At the same time, more and more Japanese people came to China. Especially in recent years, about 930,000 Japanese have come to China to recognize their ancestors and return to their ancestral home, which has set off a strange wave of returning home. What happened? What are they doing in China?

Some people think that these 930,000 people may have taken refuge in China. We all know that Japan is an island country, and it has no stable environment. Because of the movement of the earth's crust, natural disasters such as volcanoes and earthquakes often occur. In 20 1500 years, there were more than 1500 earthquakes in Japan, with an average of several times a day. This kind of living environment is frightening, so many Japanese feel that they should emigrate to other countries.

However, some people think that these immigrants must be mixed with some guys with ulterior motives. These people came to China to inquire about China in the name of confessing their ancestors. If these guys are allowed to walk around at will, China's national defense security will be greatly threatened. So we must be wary of these Japanese who come to China to confess their ancestors.
