What does Wang Wei's lovesickness poem express? What does this poem express?

Wang Wei's poem "Acacia" expresses the feelings of acacia. This is a poem that expresses the yearning for love by chanting things, and it is a work that cares about friends as soon as possible. This poem is about acacia, but the whole article can't be separated from red beans, and the name of acacia is being used to associate acacia. The original content is: When those red berries come in spring, they flush on your southern branches? People who want to miss them collect more, and Mix red beans have attracted people's attention. Red beans grow on the land in the south, and I don't know how many new branches grow every spring. I hope you can collect it as much as you like, because it can best pin your love for acacia.

The first sentence of the poem is about the origin of red beans; The second sentence asks "how many branches to send", which is very simple and vivid. If you ask nature, you will tease your feelings. Three sentences are "more choices" for friends. The words are here and the meaning is there; The last paragraph clearly shows its acacia nature. If you push it to the extreme with the word "most", then the reason for "picking more" is self-evident, and its meaning is also deeply contained. The whole poem is lively, but euphemistic and implicit, and shallow and affectionate.
