Who can give me the explanation and central idea of ??each sentence of Wang Wei's "Lovesickness"?

Acacia

Wang Wei

Red beans grow in the southern country, and a few branches will appear in spring.

I hope you will pick more of them, this is the most loved thing.

Rhyme translation:

The shiny red beans are produced in Lingnan;

Spring is here, and it is time to grow lush leaves and branches.

I hope you will pick it more often and wear it as ornaments;

This thing can best express your feelings!

This is a poem that expresses lovesickness by chanting objects.

It expresses the emotion of missing friends
