The world is diverse and bustling, and people's hearts are easily driven by fame and fortune. If you don't pay attention to correcting yourself, you will lose your true self. If a person can often reflect on his own faults, put aside his ego and consider others, he can avoid many unnecessary quarrels and create a harmonious living environment with a pure and peaceful mentality. A person who can often reflect on himself must have a noble personality, and a nation that is good at reflecting on himself must be an excellent nation.
