What is a passage that the old Taoist said to the little Taoist when the Taoist went down the mountain …

-across a door, there are two worlds. You haven't seen the world under the mountain. Good people and bad people will meet you. Have a sweet mouth, practice kung fu and don't be afraid of anything.

-Not afraid.

-Remember the master's words: You are not a hero by hook or by crook, but you are a hero by not changing your original intention.
