If I want to go to Tibet to worship, what is the correct posture?

There is no such thing as a correct posture, only a posture used by many people.

Generally speaking, the hands are closed, but the palms are hollow.

Put your hand on your forehead first, then on your mouth, and finally on your chest, representing the three secrets of body, language and mind respectively.

Then kneel down and get down in a comfortable way.

After getting down completely, straighten your hands forward and touch the ground with your elbows and forehead.

After the action can be done or not, some people will put their palms up, and some people will put their palms together again and raise them above their heads, but these are not necessary.

Then get up and the action is complete.

You shouldn't wear shoes when you do it
