I suggest you go to Guiyang Gold and Silver Jewelry City. The address is on Fushui North Road, opposite Tianheng City Garden. It can help you pick it up. Jewelry counters in major shopping malls in Guiyang can also be picked up, but the price is very expensive. Some privately-run jewelry stores can also pick it up, but the connection will be poor and the shape of the necklace will be changed.
