"The sea does not choose a trickle, so it can become big; The mountain does not refuse fine soil, and it is high. "

In fact, this sentence was later adjusted, not the original words of the ancients.

● The original text is from Li Si's "The Book of Departing Guests": "It is precisely because Taishan does not allow soil that it can become a big one; Rivers and seas do not choose trickle, so they can be deep; The king is not only numerous, so he can understand his virtue. "

The implication is that the reason why Mount Tai has such a high level is precisely because it does not reject small soil and can be piled up to form today's achievements. The reason why rivers have such a depth is precisely because they do not exclude tiny streams and converge to form today's scale.

The implication is to persuade the king of Qin not to expel talents from the six countries. It is precisely because the king of Qin did not expel these seemingly weak individuals that they gathered their strength and finally unified the world and became the "emperor of the ages."
