Comparison between Phoebe bournei and Poplar

In order to highlight the great image of poplar, the author used contrast techniques in many places. The most direct contrast is to compare poplar and nanmu, give them different symbolic meanings, and highlight the leading role of poplar.

It is through the description of plateau scenery that the author sets up a typical environment for poplars and sets off extraordinary poplars. But what the author writes is not poplars, but people's feelings of burnout, monotonous mood and internal defects after this "grandeur" and "greatness".
