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 poem describes the free and unrestrained image of thrush after it comes out. One or two sentences specifically describe the characteristics of thrush's free flight and free singing after flying. In fact, the image of thrush is a portrayal of the poet's freedom after he got rid of the shackles of the court. This poem was written when the author was exiled abroad.
