Of course, wholesale has to go to Muxiyuan area, which is the real wholesale market in Beijing. Some clothes in the zoo also come from there, right? There are all kinds of clothes. I often see several people carpooling from the zoo back to the zoo, each 30 yuan. As for the bus route, you can find it online yourself.
Cheap clothes go to Dahongmen, the next stop of Muxiyuan. Anyway, we'll know when we go.
