Please explain to the master brothers why temples charge fees in various ways.

No, Buddhism is well developed in Taiwan Province Province and Japan. When I went to Taiwan Province Province, the temples were antique, elegant and exquisite, but they were all free. You can burn free incense sticks for the Buddha at will, and you can also donate money to the charity box if you like. The monks inside are kind-hearted and the temple is sacred. Buddhism is actually restricted in China. You can see from the political books of junior and senior high schools that they advocate materialism instead of religion. But I don't think religion equals superstition. Religion is very beneficial to people. After all, law uses external coercion, while religion starts from itself. I hope you will go further on the road of Buddhism.
