It depends on what kind of hairstyle you want. If it's a perm or a hair dye, I recommend going to the barber shop on Tangshan Street (opposite the Big Buddha Temple), where there are several good prices. If you cut your hair, it can be guaranteed within 30 days (because I always cut my hair there, I recommend that I go to Yulan's house).
Then there are famous haircuts, such as a plum scissors and a beautiful baby (underground of Hualian in Wuyi Square), but only hair salons are famous and expensive.
