It's best to find someone who wears a silver needle, or go to the hospital to do laser and keep a needle for ear piercing.
In addition, recommend the American Shushu brand. Their disposable sterilized ear piercings can be done at home, which is safer and more secure.
The laser has a strong burning sensation, but the pain is ok, and of course it can be tolerated. If the price is more than 100 yuan, you should wear your own earrings and put them on directly.
