The ten iron laws of human nature
1. Couples, do not attend funerals; relatives, do not share wealth;
2. No money, do not invest in relatives; low status, do not advise others;
3. Staying too long irritates others; on a dark night, do not walk near graves;
4. Poor people, speak less; many people, do not reveal wealth;
5. Leaking wealth invites trouble; weak strength, do not bear heavy burdens;
6. Facing hardship, do not seek relatives; too much alcohol, will surely cause mistakes;
7. When guests leave, tea gets cold; acquaintances, do not work together;
8. In hardship, see people's true hearts; when people are crazy, trouble is sure to follow;
9. Officials, can oppress others; talking too much, will surely make mistakes;
10. Speaking directly, annoys others; the softer a person is, the more they are bullied.
