Du Fu's quatrains: How many colors do two orioles sing green willows?

"Two orioles singing green willows" have two colors, yellow and green.

I. Original text

"Two orioles sing green willows, and egrets cover the sky."

My window framed the snow-covered western hills. My door often says "goodbye" to ships sailing eastward.

Second, translation.

Two orioles sang tactfully among the green willows, and a group of neat egrets went straight into the blue sky. Sitting by the window, you can see the snow accumulated all the year round on Xiling Mountain, and ships from Dongwu, thousands of miles away, are parked in front of the door.

Third, appreciate

The whole poem seems to be four independent scenes, but the poet's inner feelings make its content consistent, and the fresh and elegant scenery entrusts the poet's inner complex emotions and forms a unified artistic conception. At first, he showed the spring scenery of the thatched cottage, and the poet's mood was Tao Ran. However, with the wandering of sight and the change of scenery, the appearance of river boats touched his homesickness.

On the surface, it is a vibrant picture, but in the cheerful and bright scene, it is entrusted with the poet's wasted time, loneliness and boredom, and also writes the poet's complex mood when there is a glimmer of hope. Beyond that kind of hope, it is more the poet's sadness about disappointment.
