Don't rush to buy, you can go to Xiaoying or Dazhong Temple. Ask a few more questions about the same thing and you will understand everything. These places are more formal and much cheaper than shopping malls. Don't listen to what others say, look for yourself. Also, don't forget to bargain.
3. Analysis: There is a five-ring jewelry market near Beichen, and the jewelry market in Xisiyang Hutong is cheap and good. Our friends who like studying jade often go shopping. I have a group of friends who want to love jade to study and ask questions together. Most of my friends are experts in jade, all over the country.
