Why does Li Bai have to be drunk to write a good poem by himself?

Wine has an exciting effect on human nerves. After drinking wine, people will be in a very excited state, their thinking will be more active, and inspiration will be easier to patronize, so they can write good poems. Because Li Bai is a poet, it is natural that poems written after drinking will be passed down through the ages.

In fact, Li Bai can write poems without drinking. It seems that Li Bai can only write poems after drinking because of the rendering of literati and movies in previous dynasties.
