Plastic surgery department on the second floor of the public security hospital, thirty or fifty, I forgot. There are many people selling earrings. If you want to buy something good, you can go to the mall to buy a regular one. I just had my ears pierced, so I suggest going to the mall to buy pure silver, which is better because it is not easy to get pus and bring gold. I'm not talking about gold earrings worn by women. You can go into the store to buy a gram of gold or take mom's things, melt them a little, and ask the master to give you a small gold bar with plugs on both sides.
