Tao Te Ching · Chapter 36

將欲歙之，必固張之；將欲弱之，必固強之；將欲廢之，必固興之；將欲奪之，必固與之。是謂微明。
柔弱勝剛強。魚不可脫於淵，國之利器不可以示人。

When one is about to take an inspiration, he is sure to make a (previous) expiration; when he is going to weaken another, he will first strengthen him; when he is going to overthrow another, he will first have raised him up; when he is going to despoil another, he will
first have made gifts to him:--this is called 'Hiding the light (of his procedure).'

The soft overcomes the hard; and the weak the strong.

Fishes should not be taken from the deep; instruments for the profit of a state should not be shown to the people.
