"The newcomer changed his scale. Why should he follow in his footsteps and trends? I only heard its ears and always saw the horizontal canal. " What do you mean?

This is a poem by China, which means:

Why do newcomers need to follow the pace and direction of others in exchange for good standards? As long as you hear the news in your ear, after a bumpy pass, you will see the road.

The meaning of this sentence is to encourage people to have confidence, not to be easily influenced by other people's opinions, and to have their own opinions and directions. Only through our own efforts and exploration can we find our own way and succeed.
