Tao Yuanming's poem "Drinking" says nothing about wine. Why "drinking" again?

Pointing at this and that is a common technique used by China people, especially the ancients. It is the demeanor of everyone in China to make the finishing point with the topic.

In Tao Yuanming's poems, we can see that he is intoxicated with the beautiful scenery in front of him. Even if you don't drink, you are already drunk. Isn't drinking the finishing touch?
