Leave room for everything

"Cunning rabbit three caves", do things with leeway, to keep a retreat for themselves, will not end in a fiasco. Doing everything is just like saying everything. It's not that if you hurt someone, you will be hurt by others. When things are done to the best of their ability and potential, it is difficult to change them.

There was a kind Master who passed on all the skills of his whole body to a fierce villain. The villain learned to become a master and didn't want to repay him. On the contrary, he thought that he had left his master with one more competitor. With his young courage, he dueled with his master and finally achieved his evil goal.

An example of the opposite is the story of the cat and the tiger. It's said that the cat used to be a tiger's teacher, teaching him all kinds of skills, such as power, roaring, tail curling, cutting and flapping. However, the cat thought that the tiger was bigger than itself. If it wanted to fight back against me in the future, it retained its skill of climbing trees. Sure enough, the tiger soon turned over and was angry to attack the cat teacher. The cat teacher jumped up to the top of the tree, and the tiger looked up and had nothing to do.

It can be seen from the two examples that if master keeps one hand, that is to say, he leaves himself a way out, he will not be in a miserable situation, but charity will be harmed by charity.
