Suggest going to a regular chain store. There are some old jade shops in Beishangguang and Chengdu in the southwest, which have been operating for hundreds of years. These stores are more reliable. The key to buying jade is to buy pure natural A jade, so as to preserve the value. Don't try to buy goods b or c cheaply. Although the color is good, it will fade and degum after a long time, and pure natural jade can still look good after thousands of years.
