What are the common unspoken social rules?

1. When talking to strangers, speak only three points; when talking to acquaintances, speak only five points; when talking to family members, speak only seven points. Never be too honest. Being honest with others is hurting yourself.

2. Listen to what others say and see why they say it. Sometimes the compliments given by others are not really compliments. They may be a kind reminder to you of something, or they may be mocking you. Never care about other people's superficial words. Understanding the deeper meaning will be your life-saving talisman in the future.

3. Silence is more wise than being eloquent. You never know if what you say unintentionally will be remembered by others and cause resentment. It is never wrong to say less and do more.

4. Establish good relationships with those who have helped you. The easiest way to improve the relationship between people is to ask them to do you a favor and get closer to each other.

5. One monk carries water to eat, two monks carry water to eat, and three monks have no water to eat. Never expect to have a good relationship with everyone. When there are many people, it is easy for conflicts to arise.

6. Learn to keep emotions and anger at work. Work is just work, don't make yourself unhappy. What's more, you never know if someone will snitch on you when you complain.

7. People will sincerely wish those who are sick a speedy recovery, but they may not necessarily wish those who win the lottery happiness. People's jealousy will always exist, and the imbalance in their hearts will make people do things that hurt you.

8. There are no secrets in the office. When you tell a co-worker something personal, or say something bad about someone, it may not take a week before everyone else knows what you said.

9. In the workplace, face is useless. You must learn to be thick-skinned. Why harm your own interests for the sake of face? They are all unrelated people. When they are seeking their own interests, they will stab you without hesitation.

10. Donate the charcoal in times of need to different people, otherwise you will not be appreciated by others, and you will be blamed for the poor quality of the charcoal. For example, if you lend money to a person with a bad reputation, he may not be grateful to you and may resent you for borrowing too little. He may also blame you for pressing the debt when the debt is demanded.

11. Never speak ill of someone in the bathroom, because you never know who the person next door is!

12. Your embarrassment and your face will eventually become none of your business! Unless it's a relative, there's no need to feel embarrassed or lose face. Otherwise, the debt you are too embarrassed to ask for will become someone else's money, and the person you are too embarrassed to chase will become someone else's wife.
