Chen Xi believes in the mercy of the strong. Naturally, this mercy is not bestowed upon oneself, but upon others. The same act done by different people can yield different effects.
It's like pouring tea. If Chen Xi now pours tea for an ordinary person, others will feel that Chen Xi has the virtue of respecting the wise and talent, whereas five years ago, they might not have felt anything at all.
Chen Xi remains Chen Xi; what has changed is the mindset of others. The so-called "you have changed" phrase more often reveals the change in one's own mindset.
The same behavior, done at different times, signifies completely different sincerity. Although you have not changed at all, others' mindsets have undergone drastic changes, which is the fundamental reason.
