It can be repaired in a jewelry store in binjiang road. It turns out that my wife's pendant is pearl. She dropped it while swimming and bought another one. She seems to have gone to the second floor of a jewelry store at the intersection of binjiang road and Xinhua Road. She made a hole and booked it with a *** 10 yuan, which was also quick. Just go to the jewelry store. They usually have maintenance services and don't spend much.
