As far as simple ear piercing is concerned, the right hand of Gongyuan in the south of Confucius Temple (facing the gate of Gong Yuan) is the first old man to play ~ very well. . . Many of my friends and classmates have played there ~

But if you are allergic to metals. . It is recommended to go to the hospital for consultation, because the needles for ear piercing are generally made of steel, and plastic surgery hospitals are made of steel. . . Why don't you ask Shi or the plastic surgery department of the military general hospital?

There is also hand wear, but the hole will be small, and it will be more troublesome to bring some earrings in the future ~

I hope it will help LZ.
