In fact, everyone's friends are advanced and backward. The question is how to help the backward friend to make him progress, and never follow him. This is the real "enough friend".

-Xie Juezai

Friendship was like a bright lamp in my past life, which lit up my soul and made my existence a little bit glorious.

-Ba Jin

Three friends and four friends, eating, drinking, and having fun, are called "fair-weather friends". When friends get together, they don't talk about work, study, or politics, but only talk about personal self-interest and personal resentment. This is called "living in groups all day, and words are not righteous".

-Xie Juezai

Friendship is always the assistant of virtue, not the assistant of evil. -(Rome) Cicero
