Where did you learn this subject? It is really hard to say. After all, it is difficult for everyone to adjust. Whether the hot and sour powder is good or not has something to do with raw materials and workmanship, and more to do with public taste.

The hot and sour powder around me is Xiaoxi hot and sour powder, which is located on the east side of the building of quancheng road Xitou Fisherman's Wharf. Qigong hot and sour powder on Shanshi East Road is also good. From the north gate of Shanda South School, you can see a small shop after crossing the intersection with white chicken. Hot and sour powder is very distinctive. I usually eat hot and sour powder in the snack street behind Ginza Mall, because it is close to the company.

If you really want to learn, I suggest going near Shanshi East Road first.

Good luck.
