Flowers are flying everywhere in the spring city, and the east wind of Cold Food keeps the willows from slanting. At dusk, candles were passed around the Han Palace, and light smoke dispersed into the house of the Five Marquises.
Appreciation: This poem is implicit and emotional. The first two sentences describe the late spring scenery of the capital with falling flowers and swaying willows. The word "fly" is used to describe flowers, and the word "Xian" is used to describe willows. Both are extremely skillful and expressive. The last two sentences describe an episode of palace life on Cold Eclipse Day, which is quite interesting.
