What are Du Fu's poems about Chengdu Caotang?

Du Fu's poem "Spring scenery in front of Chengdu Caotang" III.

"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.

Like four pictures, the colors are yellow, green, white and blue. The lens is close in perspective, the orioles chirping among the willows are close-ups, the egrets flying to the blue sky are close in perspective, the snow scene of Xiling nested in the window is perspective, and the Wan Li boat moored in Wu Dong is somewhat imaginative and full of colors.

PS: Chengdu Du Fu Caotang:

During the war-torn exile in Chengdu, Du Fu, with the help of his friends, built a thatched cottage on the banks of Huanhua River in the western suburbs of Chengdu. He lived here for four years and became the peak of his poetry creation, writing more than 240 poems. The famous "Delighting in Rain on a Spring Night", "Autumn Wind Ruins the House" and "Book of Appreciation" are all written here.
