Why is it true that the same surname was a family 500 years ago?

This statement has existed since the last century, and it is probably the early years of the Ming Dynasty to push forward 500 years. The early Ming Dynasty just experienced war and famine, and the population in most parts of northern China dropped sharply. In order to maintain the rule of the Ming dynasty and resume production, the Ming court decided to emigrate from Shanxi to Shandong, Hebei and Henan. More famous is the pagoda tree in the north of Hongtong County, Shanxi Province. . "Ask me where my ancestors came from, Shanxi Hong Tong Sophora japonica. What is the name of the ancestral home, the old stork nest under the big locust tree. " For hundreds of years, this folk song has been widely sung in the Jianghuai area of Lu Yu, Beijing, Tianjin and Hebei. Under the ancient pagoda tree in Hongtong County, whether it is ice and snow, or hot summer, wanderers from afar are in an endless stream, some seek roots to worship their ancestors, some pay homage, some leave poems to mention words, and some donate money and materials. At the time of parting, like their ancestors, they lingered and looked back frequently, unable to bear to leave. Over time, the tree shape of ancient Sophora japonica in Hongtong County has become a unique root-seeking culture. An ancient pagoda tree has become the source and origin of blood for thousands of children in Qian Qian, China.
