About family planning. In the 1980s and 1990s, some Liangshan Yi people considered childbearing to be the greatest meaning of their lives, otherwise their lives would be meaningless, and getting rich and getting promoted were secondary. Due to major political conflicts, they gave up their homeland, avoided fines, brought food and seeds, climbed over Tuowu Mountain, crossed the Dadu River, crossed the Niba Mountain, and came to Yingjing County, Ya'an, Sichuan, to open up wasteland and cultivate the land. People followed one after another, and now two Yi townships have been formed, with administrative establishments, Minjian Township and Baofeng Township, now a tea township with a population of about 8,000. They have made outstanding contributions to population development and have lived a happy life. Their first principle concept is that the house is not important, and remembering the family tree is the most important thing. Usually, two families that can intermarry will make an appointment to move far away, putting people first and walking the earth.
