Xuantang's understanding of repaying kindness is to keep him safe throughout his life, protect him from dying naturally, repay the kindness and return home as soon as possible.
Zhao Shuo looked at the little girl who claimed to be penniless, and understood that she had nothing to repay for her kindness, so he pledged himself to her.
At first, Zhao Shuo looked at the little girl and thought: She should be an adult, right?
Later, Zhao Shuo thought about whether I should agree to repay her kindness? Is it a promise? Or agree?
Intention: Help each other, love each other, and be kind to others.
