Take this poem as an example.
The first step is to talk about the realm.
The poem points out that the whole world loves flowers, and only I love bamboo, because flowers are so delicate that the snow will go with them overnight, and bamboo will bring a new green to the world whenever and wherever.
The second step is to talk about skills.
The strongest technique of this poem is contrast, which shows that although flowers are colorful, they are only flashy after all. With the perseverance of bamboo, it is compared with flowers, which highlights the nobleness and purity of bamboo. (I'll leave the other technology to you.)
The third step is to talk about feelings.
This poem expresses its secular concept in an ideographic way, advocates the noble character of perseverance, silent dedication and outward unity, and shows the noble quality of the author beyond secular life.
You can follow this step and write another one yourself. Just try it. It should work. Welcome questions.
