I want to be a monk for a week and experience the purity of becoming a monk. Can I go to Wutai Mountain?

Wutai Mountain is not suitable. There are many tourists and it's not very quiet. I suggest you visit some temples nearby. Talk to the host, and he will agree. However, you should consciously help the temple do something you can, and you should pay for your own meals and fires. Because the monk's meal is provided by ten parties, you have no right to eat it for free. I have to pay some alimony. I hope you can get peace these days!
