Brief comments on characters:

In the original work, He Chao once had a "work" called "The Back", which is also one of the famous scenes in the original work. This is actually an unconventional composition written by He Chao on purpose, mainly to praise his handsome back. He Chao's own back appeared in the cartoon, but unfortunately it was only the back of the Q version. I don't know if you can feel his handsomeness from the back of He Chao's Q version.
