Does Dr. Jiang sell shoes? What's the difference with ordinary shoe stores?

It must be different. I just passed by Dr. Jiang's shop last time. In fact, I didn't buy it in the end, but the clerk's attitude was still very good, because I only had dozens of dollars on me that time. I was going to take the children for a walk. Later, I thought this pair of healthy shoes was really necessary, so I bought them the next day.
