Why did Lao Zhang's family migrate 600 years ago in Hongdong County, Shanxi Province?

The Ming government (Hongwu and Yongle) forced large-scale migration 600 years ago because of the war in the late Yuan and early Ming Dynasties and the Jingnan War in the early Ming Dynasty, the Central Plains was barren and was blocked by Taihang Mountain and Luliang Mountain. At this time, the Jinnan area irrigated by the Yellow River developed well and its population increased rapidly. According to the records of Shanxi immigrants? In the twenty-four years of Ming Hongwu, the total population of Shanxi Province was 5.65 million? Pingyang Prefecture accounts for 6.5438+0.84 million, reaching 38%? The state capital is only 850,000, accounting for only 17.5% of the total population. In the fourteenth year of Hongwu, the population of Henan was more than 654.38 +0.893 million, and the population of Shanxi reached 4.03 million 454. It is equivalent to the combined population of Hebei and Henan. After four years of Hongzhi, the population of Henan Province was equal to that of Shanxi. Shanxi is densely populated, and southern Shanxi ranks first. Hongdong is a densely populated county in Pingyang. Hong Tong is located in the traffic artery, north to Youyan, east to Qilu, south to Qin Shu and west to Helong. Although it is not specially used to move Hongtong people, it naturally takes Hong Tong as the focus of moving people.
