Why do people with the same surname say that they were a family 500 years ago?

About 600 years ago, in the Ming Dynasty, the population of Henan, Hebei, Shandong, Anhui, Jiangsu, Shaanxi and other regions in the Yellow River and Huaihe River valley decreased greatly in the early Ming Dynasty. By the fourteenth year of Hongwu after the war subsided, the population of Henan and Hebei provinces was not as good as that of Shanxi Province. However, due to its unique geographical location and less wars, Shanxi's production still has a certain development. Coupled with the influx of refugees, its population has increased dramatically. Therefore, the Ming government immigrated from Shanxi to all parts of the country many times during the Hongwu and Yongle years. One of the most famous immigrants is Sophora japonica in Hongtong County, Shanxi Province. According to the records of official history notes such as Ming History, Shi Ming Lu and Rizhi Lu, as well as the genealogy and inscriptions collected and consulted by experts who study Hongdong immigrants, incomplete statistics show that the immigrants of Sophora japonica in Hongdong in Ming Dynasty were distributed in more than 500 counties (cities) in 18 provinces (cities), including 65438+ in Henan. There are 62 counties (cities) in Jiangsu, Anhui, Hubei and Hunan, 5 1 county (city) in Shaanxi, Gansu and Ningxia, 34 counties (cities) in Shanxi, 8 counties (cities) in Inner Mongolia, Liaoning 1 1 county (city) and 3 counties in Jilin.

According to conservative estimates, there are 200 million descendants of Hong Tong Sophora Immigrants, all over the country and even overseas. It can be said that where there are Chinese, there are descendants of Hong Tong Huai immigrants. According to some scholars' calculations, half of the people in the country are descendants of the immigrants from Hongtong pagoda tree.

In other words, about half of the people in the country are descendants of Sophora japonica who immigrated from Hongtong County, Shanxi Province more than 600 years ago, and their surnames have been passed down from generation to generation. So, back to 600 years ago, their ancestral homes were all in the same place, and naturally people with the same surname were a family.

Five hundred years ago, a family came from this, but this sentence was a long time ago, and it should be more than 600 years now, but it still means that.
