Two orioles sing green willows, and a row of egrets walk in the sky.

It means that two orioles sing tactfully among the green willows, and a group of neat egrets go straight into the blue sky.

From the quatrains of the Tang Dynasty poet Du Fu, the original poem is as follows:

"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.

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.

Extended data

The poem Jueju is beautiful in itself, with four antithetical sentences. There have been quatrains since the Six Dynasties. After the Tang Dynasty, quatrains became a very mature art, and many famous poems in history used quatrains.

A quatrain is four sentences, and the four sentences often don't match, or the first two sentences of the four sentences don't match the scenery and the last two sentences don't match the lyric, or the first two sentences don't match the last two sentences, so now all four of his poems are matched, which can be said to be a very neat and attentive poem. Du Fu once wrote a poem that made people "swear, not surprisingly, never stop", so he put it into practice.
