Ye Tianchen is assertive, and the root of his assertiveness is that others are also assertive toward him. After all, Ye Tianchen deeply understands that for those who are assertive and arrogant, you must be even more assertive and imperious to avoid being passive!
Life is ultimately about striving. In a mere few decades, if not for the struggle of survival, then what is the purpose? When others are assertive, disdainful, or even attack you, should you kowtow and greet them with a smile? There's no need for that. "If people don't offend me, I won't offend them; if they offend me, I'll retaliate." This is Ye Tianchen's principle and his character.
