What does it mean to go home without drinking?

"When we meet, we will return without drinking, and the peach blossoms at the mouth of the cave will also make people laugh" is a sentence in Zeng Wenxian's article.

The peach blossom at the mouth of the cave is the peach blossom at the mouth of the mountain river. Because it seldom sees sunlight, it is very weak.

Therefore, it is not qualified to laugh at people, but if you don't drink empty when you meet, the peach blossom at the mouth of the cave can laugh at you, with a strong tone.
