The theme of the poem is the courtyard landscape seen by the poet after his nap:
The poet should have had a drink before taking a nap and said he was drunk. The poet said that he was ruined by the smell of melons and fruits because he smelled them. This sentence is very special.
Moreover, this melon smells better than the wine you drink, so the poor people who only know how to drink don't know how to drool if they smell this melon. (drinkers may laugh at the poet himself, or they may)
The heart of a bull means purple and black. This couplet actually means that the plums in the yard are all ripe, and they all hang down, looking like lotus from a distance.
The third triple means that plums bloom in the afternoon and only in the morning (smile means smile, which means that the fruit is red here) (it seems that poets think that fruit is a very sad thing-many poets have this idea that flowering is the most beautiful period, and the result is like the fading of youth).
The last couplet says that naughty children have long discovered that plums are ripe and there are already plums to eat on the ground. Then, the evening breeze blows and the leaves rustle-it's time for the poet to get up and eat. The ending is very dull. Very active, very leisurely.
