Pour a glass and frown. Heaven and earth, good idea. How to understand this sentence?

Interpretation: Isn't it a pity to pour a full glass of wine on the ground? On the contrary, it will make you frown, feel comfortable and clear-headed, so as to get the best solution to the situation. As the saying goes, wine is difficult to understand. Some people say that it is better to add a cup after being drunk than nothing. Then, what looks like a small profit is actually the temptation of great harm. Don't we turn harm into benefit by giving up on our own initiative? Heaven and earth, dry and Kun, form an invincible divination. When you stop misbehaving and pour out a glass of wine that doesn't belong to you, everything starts from scratch and everything is fine. Isn't this a great thing that makes you feel very happy?
