When did Shanxian people in Shandong move in?

After the war at the end of Yuan Dynasty, after more than 20 years, Zhu Yuanzhang unified the world. However, at this time, the mountains and rivers were devastated and devastated. Shandong, Henan and Hebei are mostly uninhabited areas. In order to restore agricultural production, develop the economy, balance the population, make the world peaceful and consolidate the rule of the Ming Dynasty, the rulers of the early Ming Dynasty adopted an immigration policy and moved in according to the proportion of "four families in one household, six families in two households and eight families in three households". According to research, during the fifty years from the early Ming Dynasty to the fifteenth year of Yongle, people from fifty-one counties in Shanxi Province were evacuated and sent to Beijing, Hebei, Henan, Shandong, Anhui, Jiangsu, Hubei, and so on ... all over half of China. The pagoda tree of Guangji Temple in Hongdong, Shanxi Province is the place where people go through the relocation procedures. Legend has it that the government once took the form of deception: the government posted a notice in advance, saying that people everywhere would move except those under the big locust tree. As a result, when thousands of people gathered under the big locust tree, the officers and men were surrounded on all sides, and all men, women and children moved. When they set foot on the journey at the urging of officers and men, they turned around while walking, and finally only saw the big locust tree and the old man's nest in the distance. Therefore, the locust tree and the old man's nest have become the symbol of Shanxi immigrants bidding farewell to their hometown.

Today, descendants of ancient locust immigrants have spread all over the world. Millions of people are homesick for their homeland and seek their roots and ancestors. This ancient pagoda tree has become a popular place for people to worship their ancestors. The "Root-seeking Festival" held in Hongtong County from April 1 day to 10 every year attracts more than1000000 Chinese at home and abroad to come for sacrifices and sightseeing.
