Song Ouyang xiu
The cries of thousands of birds echo their own hearts, and thousands of purple flowers on the mountain are on the height of trees.
Only then did I understand that listening to the cry of the thrush locked in a golden cage is far less than singing leisurely in the forest.
The meaning of this poem is:
Hundreds of birds are echoing at will, just on the colorful trees strewn at random.
Only then did I realize that the cry of the thrush in the golden cage I heard before was far less than the spontaneous singing when I wandered in the forest.
The first two sentences of this poem describe the scenery: thrush birds sing everywhere, one high and one low, making the colorful mountain flowers more pleasing to the eye. The last two lyrical sentences: Seeing those birds in cages, I really envy thrush flying in the forest, free and unrestrained. Ouyang Xiu, the author, was banished to Chuzhou at this time because he was banished to the DPRK, so he used "locked in a golden cage" as a metaphor to express the poet's psychology of breaking free and yearning for freedom.
