Do I need to make an appointment to enter Chengdu Daci Temple?

Don't. According to the public comment website, Chengdu Daci Temple is located in Taikooli, a bustling area in downtown Chengdu. Like many temples in Chengdu, this temple is free of charge. No need to make an appointment in advance. You can go in and out at will by scanning the place at the door to check your temperature.
