Where can I sell crystal balls in Shanghai?

There is a Crystal Street in the Town God Temple, indoors. It looks more formal and things don't look fake. I used to walk around it with others and touch each other with static electricity. There are many crystal shops in it, which is also convenient for you to shop around. My classmate bought it in it before, and she said it was not bad. The price can also be negotiated. If you are still worried about the quality of crystal, I suggest you refer to it, and then go to the nearby Yayi Gold Store or Old Temple Gold, which is more authentic. However, there is also a small commodity wholesale market near the Chenghuang Temple, which also contains so-called crystals. I don't know if it's true or not, so I need to identify it myself.
