As we all know, we and our neighbor Japan have a deep relationship since ancient times, but when it comes to the origin of Japan, we can always think of Xu Fudongdu. Yes, it is indisputable that Qin Shi Huang sent Xu Fu out to sea to seek the elixir of immortality, but where Xu Fu went, we do not know. Although most of us believe that Xu Fudong crossed to Japan, the lack of sufficient historical evidence also makes this matter confusing!

However, although we cannot prove the authenticity of Xu Fudong's crossing to Japan, more than 400 years later, a person went to Japan again with more than 2,000 Chinese, and lived there, which has been passed down to this day, and this person has also become the "second Xu Fu" in China! However, this person's deeds are recorded in the history books of China and Japan, and even the Japanese can come up with a family tree to recognize the ancestors, so the authenticity of this matter is beyond doubt!
This matter should start from the Eastern Han Dynasty. At the end of the Eastern Han Dynasty, the world was in chaos, and the masses rose up to chase the deer in the Central Plains, but the most surprising of them was that Cao Cao blackmailed tianzi to order the princes. We know that the Son of Heaven at that time was Liu Xie, the Emperor of Han Xian, but after Cao Cao died and Cao Pi ascended the throne, Emperor Xian of Han was forced to abdicate the throne, was given the title of Duke of Shanyang, and lived a "free and free" life in a small place.
In Liu Azhi's generation, that is, the grandson of Emperor Xian of Han, it was the Western Jin Dynasty. We know that the Jin Dynasty seemed to be a period of great unification, but in fact it was very chaotic, when ethnic minorities from all over the world entered the Central Plains and stirred up the Central Plains. Liu Azhi also saw that he was about to "change the heavens" again, and besides, he was still the orthodox Han Dynasty, in case someone took me for something, wouldn't it be very unjust? Therefore, on the 1st day of the lunar calendar, he summoned the old ministers of the Han Dynasty to discuss the matter of Dongdu!
Liu Azhi immediately said that if he stayed here, I was afraid that there would be a disaster of killing himself, and he heard that there was a Japanese country in the east, and we could take refuge. In this way, Liu Azhi led his son Liu Duhe, his uncle Zhao Youde, and his clan members Liu Guoding, Liu Taozi, Liu Heming and a total of 2,040 men and women, leaving Mainland China, crossing the ocean, and after several difficulties, they finally arrived in Japan on September 5, 2019, emperor of Japan!
After Liu Azhi arrived in Japan, the emperor was very happy, and not only found a place to settle them down, but also made Liu Azhi the envoy of the Eastern Han Dynasty. Subsequently, it is estimated that Liu Azhi felt that this place was not bad, so he asked the emperor to recruit his fellow villagers from Baekje, Silla and other countries to Japan.
At that time, Japan still admired China, so the visitors did not refuse, and arranged them to be sent to various parts of Japan. There is no way, there are too many people, and the Japanese area is not big enough, only to live separately, in fact, this is also conducive to social stability, after all, a group of foreigners gathered together is easy to breed trouble, not easy to manage. In this way, more Chinese came to Japan to live and passed down to this day! It can be said that some Japanese people do have the blood of Chinese.
In fact, Liu Azhi's contribution to Japan is not only to bring the population so simple, but also to bring advanced culture, technology, and higher level civilization, and promote the development of Japanese social productivity and civilization! However, after all, in a foreign country, Liu Azhi's descendants did not continue the "Liu" surname, but changed to Japanese surnames, such as the famous Ōzo clan, Sakaue clan, Harada clan and so on are basically his descendants.
Liu Azhi and his descendants held a high position in Japan, and even influenced the course of Japanese history, and those big families still exist to this day. For example, the Harada family has its own family tree, which has been passed down to the 93rd generation of Liu Bang, and also built a Han Taigong Temple in Fukuoka City, Kyushu, and regularly worships Liu Bang and other distant ancestors. Moreover, their descendants also built the Azhi Palace to sacrifice Liu Azhi and others, it can be said that without Liu Azhi, there would be no them now, and even some netizens said that they wanted to come to China to worship in front of Liu Bang's tomb in person!
However, the most painful thing is that Liu Bang's descendants went to Japan with advanced culture and technology and made great contributions to them, while a thousand years later, they came to China with guns. The Battle of Baijiangkou in the Tang Dynasty, the Wanli Korean War in the Ming Dynasty, the Sino-Japanese War in the Qing Dynasty, and the War of Resistance Against Japanese Aggression, I think, all of them have the shadow of Liu Azhi's descendants. Some of them left here, but they came back with guns, and they don't know how to feel?
