A person's self-cultivation is mostly reflected in two aspects: courtesy and respect. Let's talk about discretion first. For example, when taking care of others' feelings in public to restrain your behavior, you can't go your own way and obey orders. This is the most basic accomplishment. When you see someone older than yourself, you can take the initiative to stand up and give up your seat and ask the other person if I can smoke. This is a manifestation of self-cultivation, and self-cultivation is also a kind of self-cultivation.
A cultured person knows how to respect others better. A cultured person will not look down on a person because of his position or whether he has money. Maybe he is just a beggar, but he still treats him with due respect. In his eyes, everyone is equal. This is the most cultivated character.
I once heard a saying that others respect me not because of my noble status, but because the other person has cultivation.
