Chow Tai Fook doesn't sell silver ornaments, and 500 yuan doesn't seem to sell earrings (I bought such a big pair of silver chopsticks before I went to 400 yuan).

I don't think it's good to wear silver on an inflamed ear. I suggest that she apply some iodine or erythromycin, and it will be fine in two or three days. Plastic can also be used. It's good to bring gold.
