First seen in Lao Tzu's Tao Te Ching, the original text is as follows:

I have three treasures that I hold and protect: one is kindness, the other is frugality, and the third is not being the first in the world.

There are deep philosophical thoughts in it, which can't be explained clearly in a few words.

Generally speaking, "not daring to be the world" means not being self-righteous, not noble, modest in everything, not arguing with others about right and wrong, and not striving for fame and fortune. Suffer hardship first, enjoy it later, sacrifice yourself for others, serve the public wholeheartedly, have no self-interest, only know how to give and ask for nothing in return. Enjoy the joy of the world and worry about the worries of the world.

Later, Dr. Sun Yat-sen did the opposite, put forward the slogan of "Dare to be the first in the world" and put it into practice, clinging to his ideals all his life.
