Yichun people enter! If you go to Chenghua Temple to ask for amulets, will it be useful? How much is one?

My mother seldom goes to the Diagenetic Temple, but usually goes outside to buy some amulets. I don't remember how many amulets I spent, 50~ 100. I didn't ask my mother if it was expensive, so it was useless. Hehe, I decided it was useful, but it was useful. I didn't bring much anyway.
