In the summer of 2022, we came to a pure land cut off from the pandemic—Sihe Township in Daliangshan, Sichuan—to carry out public welfare poverty alleviation. This is a nationally renowned poor mountainous area. Although it is not far from Xichang, the mountain roads are narrow, making it almost impossible for large vehicles to pass each other. Along the way, we saw Yi women carrying goods on their backs in baskets, and the view was filled with clusters of rammed-earth houses.
