Specifically, a gentleman has three fears: fear of destiny, fear of nobles, and fear of the words of saints. According to master nan huaijin's explanation, "fear of fate" includes all religious beliefs, belief in God, domination and Buddhism. A person can only succeed if he is afraid, and he can't succeed if he is fearless. "Fear of adults" refers to fear of parents, elders and people with moral knowledge. Only in this way can you succeed. "Fear of saints" refers to the remarks left by people who fear sages, all of which are the refinement of sages' life experience. "Three friends" also comes from what Confucius said: "The winner is three friends, and the loser is three friends. Friends are straightforward, friends forgive, and friends listen more, which is beneficial; Friends will be very open, friendly, soft and painful. "
