The meaning of the poem "Drunk in the Flower Field"

When I found Fangfei, I was intoxicated by the wine, leaning against the flowers and trees to sleep soundly. The red sun was already setting in the west. And after the guests had dispersed and sobered up late at night, they held red candles and admired the remaining flowers alone. The tulips of the Netherlands and the lavender of Provence flashed into my mind without thinking. Drunk - of course it's wine. There are flowers, fields, and drunkenness, which is beautiful.
