1. My life has a limit, but my knowledge has no limit. "Zhuangzi·Health Preserver"

Human life is limited, but knowledge is infinite. Use your limited life to devote your limited life to unlimited learning.

2. Phase and nothingness, mutuality and nothingness, mutuality and nothingness. "Zhuangzi·The Great Master"

Being friends with each other is in non-friendship, and doing things with each other is in doing nothing. To make friends, friendship should be achieved without intention, and mutual help should be achieved through inaction. This is the "irreconcilable friendship".

3. Nothing is other than what it is, and nothing is other than what it is; if you know yourself, you will not see it, but if you know yourself, you will know it. Therefore, it is said: He comes from this, and this is also caused by that. "Zhuangzi: Equality of Things"

Everything in the world has an opposite side, and everything has an opposite side. What is not clear from the other side can be seen more clearly from this side. Therefore, the other comes from this, and this cannot be separated from the other. That is to say, there are two opposite sides of things, and no one can live without the other.

4. Don’t you know that your husband is a mantis? It is the beauty of his talent that he is angry and makes his arms feel like ruts, not knowing that he is incompetent. "Zhuangzi·Human World"

Don't you know that mantis? It danced its two sword-like arms in an attempt to block the advancing wheels. It doesn't understand that its own strength is completely incompetent, but it self-righteously believes that its abilities are very powerful. The allusion to the idiom "a mantis with its arms like a chariot" comes from this, which is a metaphor for overestimating one's own capabilities.

5. Mountain trees are invaded by invaders, and burned by fire. Gui is edible, so cut it down; lacquer can be used, so cut it. Everyone knows the uses of useful things, but no one knows the uses of useless things. "Zhuangzi·Human World"

The trees growing on the mountains were cut down because of natural needs; the ointment was burned because it could illuminate; the osmanthus tree was cut down because it was edible; lacquer could be used, so Skinned. Everyone knows the uses of useful things, but not the uses of useless things. Being useful and doing something will be harmful, but being useless and doing nothing is a blessing.

6. When the spring dries up, the fish and the fish are on the land. They wet each other with their crotches and wet each other with foam. It is better to forget each other in the rivers and lakes. "Zhuangzi·The Great Master"

There has been a long drought without rain, and the river has dried up. Many fish were trapped on the beach in the river. They relied on each other closely, opening and closing their mouths to spit to moisten their bodies (in order to delay their lives and wait for the heavy rain to come). It would be better to forget each other in the rivers and lakes. It is a metaphor here that people should forget life and death and wander in the land of great roads. The idiom "to moisten each other with foam" (also known as "to moisten each other with foam") comes from this.
