Why do Japan and North Korea say that their ancestors were from the Northeast?

China is one of the four ancient civilizations with a history of 5000 years. Japan and South Korea near China have been studying the origin of this country. As for the origin of Japan, scholars have long believed that the ancestors of Japan originated in China, and there are many theories to prove it, but careful analysis will still reveal some loopholes. A Japanese historian said, "Count our ancestors. It can be said that every modern Japanese has inherited the blood of all Japanese people a thousand or hundreds of years ago. So we must admit that no matter whose blood we have, it contains 10% or 20% of the blood of ancient naturalized people. Although people whose ancestors were assimilated and naturalized are very popular, this is not the case. Naturalized people (Han immigrants) are our ancestors. "

Obviously, Japan is separated from us only by a water, and it has many ties with China, including diplomacy, war, art, science and technology, etc. Another important thing is immigration. Many China people crossed the sea to Japan through Korea, Shandong and other places and became the ancestors of many Japanese people. Since the pre-Qin era, mainland immigrants have continuously entered the Japanese archipelago. In the Japanese history books "Ancient Records" and "Journal", foreign immigrants are called "Han", "Imam Ashito", "Wu", "Tang" and "naturalization". The migration of mainland immigrants to the Japanese archipelago can be divided into four periods, namely the Qin and Han Dynasties. Wei, Jin, Southern and Northern Dynasties; Sui and Tang dynasties; Song, Yuan and Ming Dynasties. In order to absorb advanced culture and introduce technical talents, the Japanese government sent many envoys to Chinese mainland and the Korean Peninsula to seek and persuade Han Chinese to come to Japan. All these factors have promoted the climax of mainland immigration to Japan.

The most popular legend in this period is that Xu Fudong crossed Japan during the Qin Shihuang period. There is a record in Sima Qian's Historical Records of Qin Shihuang's Biography that Qin Shihuang acceded to the throne 28 years ago: "Qi (Xu Fu) and others wrote that there are three sacred mountains on the sea, named Penglai, abbot and Yingzhou, where immortals live. Please ask the boys and girls quickly. So he sent thousands of men and women from Xu Fufa to the sea to find immortals. " So, where did Chui fook finally buy medicine? According to Records of Historical Records and Biography of Hengshan Mountain in Huainan, Xu Fu finally reached the land of "plain luster" and "the future of kings". It is said that this "plain Hirozawa" is Kyushu in Japan today. In Japanese academic circles, there are many academic groups, scholars and experts who study Xu Fu's deeds. There are many articles, books and monographs about Xu Fu's deeds, which confirm the fact that Xu Fu arrived and developed in Japan. Xu Fu is still respected and loved by the Japanese people.

At the beginning of this article, Chao Heng quoted a poem by one of the most famous international students (Japanese name is Abe Ma Zhong Road) Li Bai. Send envoys of the Tang Dynasty back to Japan. The Tang Dynasty sometimes sent envoys to accompany them. Because of difficulties in navigation, they often stay in Japan and become naturalized. For example, Shen and Yuan Jinqing both work in the Japanese government. Monks in the Tang Dynasty also sent envoys to Japan, the most famous of which was Du Dong in Jian Zhen. Interestingly, with the large-scale personnel exchange, there have been many transnational marriages between China and Japan. For example, Ambassador Qinghe Fujiwara of the Tang Dynasty was sent to marry a China bride. It can be seen that transnational marriage is not only a fashion today, but also relatively popular as early as 1000 years ago in the Tang Dynasty. After the Anshi Rebellion, the Tang Dynasty weakened, the vassal states were divided into free states, and the people were struggling. At this time, until the end of the Tang Dynasty, there were also many people in China Eastern Airlines, but its scale could not be compared with that of the Jin Dynasty. There is even a legend that Yang Guifei was not hanged at Mawei Post Office, but fled to Japan with the messenger. It is said that some people in Japan claim to be their descendants.
