Introduction to Agriculture in Dazhai: The natural conditions of Dazhai are very harsh and it is a poor mountain village. After liberation, under the leadership of Chen Yonggui and Guo Fenglian, the people of Dazhai were determined to organize themselves to change the backward appearance of the mountain village. In 1963, Dazhai suffered a devastating flood, resulting in mountain torrents, land erosion, house collapse, and kiln collapse. The people's lives were very difficult, and ten years of hard work were wasted. Under the leadership of Comrade Chen Yonggui, a wave of self-reliance and hard work was launched to rebuild the homeland.
