To understand this poem, you also need to know a historical fact, that is, in the past, foreigners insulted our nation as the "sick man of East Asia" and "a piece of loose sand." Although this is not necessarily entirely true, it does reflect some phenomena in which the spirit of our nation being humiliated under the invasion of foreign powers has been distorted.
It was with the poet's sensitive spiritual feelings and sharp political vision that Ai Qing deeply understood the trends of the times and the pulse of society, and realized that the awakening of our nation has come, and then "each other" from the wilderness. The image of a tree "standing alone" was inspired, producing the association of "in the invisible depths/their roots are entangled". Ai Qing gave each of the trees growing on the earth a living character, and with a unique vision saw the potential fact that "under the cover of soil/their roots are stretching", he regarded them as a great nation in the process of progress. A symbol of unity and strength. His artistic expression allows people to gain a poetic pleasure and gain philosophical understanding through the observation and integration of life phenomena.
