There is a dragon wonton soup on the right hand side of Chunxi Road in East Street. There are many Chengdu snacks in it, which are complete and delicious, but they are often crowded. If you don't want to squeeze, you'll miss your meal. Try it.
There is a Zhong Kui on the left at the other end of Zongfu Road, which is a little hidden. Please pay attention. It is famous for jiaozi, and there are other snacks. It's also crowded.
