Jiuzhaigou is composed of nine Tibetan villages distributed in three mountain ditches, of which Shuzhengzhai is the largest stockade, located next to Shuzheng Waterfall. Shuzhengzhai has now developed into a tourist gathering place, with Tibetan hotels, restaurants, and local specialties for sale. Most Tibetan compatriots are very enthusiastic and greet tourists warmly. They provide free tea and seats for tourists to rest, and repeatedly explain that it is okay to buy or not to buy things.
