I don't know if you are talking about "learning from Dazhai". "Learning from industry is a great success, and learning from agriculture is a great success" is a political slogan starting from 1964, which has both positive and negative lessons in modern China. Later Dazhai was no longer a simple production brigade. To understand Dazhai, you have to understand Chen Yonggui.

Dazhai Town Dazhai Village, Xiyang County, Jinzhong City, Shanxi Province

Dazhai Village, the first village in China, is a small mountain village in Xiyang County, Jinzhong City, Shanxi Province. Here is a barren land, the natural environment is harsh, and people's lives are very hard. Later, mountain management and water control were carried out, and layers of terraces were opened on the slopes of seven ditches and eight beams, which changed the situation of relying on the sky to eat by diverting water. Therefore, it was affirmed and praised by President Mao Zedong, and issued the call of "learning from agriculture" in 1964, thus becoming a banner of national agriculture.
