What does Zitang really teach in convex and concave college?

The son of the little Spartan model, Shinrikyo in Tang Dynasty, is in the convex-concave college. Zi Tangzhen, a character in China's cartoon "Bump World" and its derivative works, belongs to the Phantom Animal Star Zitang family and is Zi Tangzhen's brother. He is firm in character, strictly abides by the rules, fulfills his obligations, is meticulous in doing things, treats people gently and has strong taming power. The players in the last concave-convex contest were demoted in the last concave-convex contest and transformed into Z angels by the angel of life. In Zitang's fantasy memory, Zitang did show a very powerful taming power, and in Zitang clan, besides Xiaosan, he was the only one who was good at Zitang, and gave him a model of Little Sparta (this is the source of Zitang's magical power of Little Sparta). According to the setting, it was erased after a fall and became a Z angel.
