What is a flood?

The first sentence of Qian Wen Zi, an ancient enlightenment reading, says: Heaven and earth are mysterious and the universe is vast.

It means: At the beginning of the world, the world was in a state of chaos and ignorance.

Among them, "The Great Wilderness" comes from Yang Xiong's Xuan Jing in the Western Han Dynasty. A flood is a flood; A wilderness is a wilderness.

When the ancients talked about "wilderness", they all meant ancient times. For example:

Xu Ling in the Southern Dynasties "Shooting Book with Yang Servants in the Northern Qi Dynasty": "Those who are self-sufficient will eventually be quiet."

Song Yang Wanli's On the Wind of Chinese Emperor's Sages: "In the wild world, there is no difference between man and bird."

(At present, it has become the "power of the wild" of online hot words, which comes from the lines of the magic drama "Hua" and is a joke. )
