If you are afraid of infection and want to find a safer place, you can go to the beauty department of the hospital. There is one in the Third Provincial Hospital, and my friend used a needle instead of a nail gun to give some anesthetic, so it didn't hurt to fight and the infection rate was relatively small. Hit a person there for about 40, and there is no limit to the number of ear holes, so the more you hit, the more you earn, hehe. I suggest you bring pure gold or sterling silver earrings after playing, which is beneficial to maintenance. Pure gold is the best. The laser ear hole is not clear.
