Lin Yang's Cultivation of Immortality:
The three obediences and the four virtues are: never show off, never be soft-hearted, never make enemies, be vicious enough, be despicable enough, and be cautious enough.
Those who pretend to be cool are all idiots. One day they will encounter a tough situation and they will die without knowing how.
If you are soft-hearted, you will not be able to do dirty work, and you will definitely die of poverty.
The most important thing is not to make enemies. There cannot be such creatures as enemies at all. If there must be enemies, they must be killed on the spot and must not be kept overnight.
As for cruelty, despicability, and caution, they are basic moral qualities.
