When I visited the temple, I found that all the gates were closed, only looking at the small doors on both sides. What is the reason?

The three doors symbolize wisdom, compassion and convenience from the left and right. Usually only open the small doors on both sides. First, it means that there are no major activities in the temple. The second is to make all beings ignorant (it is best not to enter the temple through the middle gate, which is too disrespectful to the Buddha). Only on the fifteenth day of the first lunar month, or when Buddha and Bodhisattva celebrate Christmas or have major Buddhist activities, will they open the door, because at this time, Buddha and Bodhisattva will facilitate all beings not to care.
