What did Su Shi use to praise Liu Jingwen's character and moral integrity in his poems to Liu Jingwen to express his admiration?

In his poems to Liu Jingwen, Su Shi praised Liu Jingwen's character and expressed his admiration for him.

The lotus in the lotus pond, where the green leaves and red flowers once reflected the sun, has long withered, and the withered stems and leaves can no longer hold the green umbrella to keep out the wind and rain; The residual chrysanthemum under the independent hedge, although the stem is fragrant, has no leaves, and only the tall and straight branches are still strong against the wind in Ao Shuang. However, whether it is thanking first or thanking later, it is out of date after all, and we have to withdraw from the competition and give way to the vibrant early winter pride-oranges and oranges. At this point, the poet happily reminds people: Please remember that the best scenery in a year is in the early winter when the article is brilliant (Qu Yuan's Ode to an Orange). When oranges are mentioned side by side here, they are actually biased towards oranges. From Qu Yuan's Ode to an Orange to Zhang Jiuling's experience (here, south of the Yangtze River, there is a red orange tree. ), oranges have always been praised by poets as "good trees", while oranges are actually "although they may serve your distinguished guests". Citrus's "leaves are green all winter" and "but it is used to cold because of its' nature'" are not only inferior to lotus and chrysanthemum, but also want to be comparable to pine and cypress.

Therefore, the poet expresses Liu Jingwen's character and moral integrity, surpassing the lotus leaves and chrysanthemum branches, reaching the level of dried tangerine peel, which can be compared with pine and cypress. The whole poem focuses on the last sentence, not the previous one.

The original text is as follows:

Go to Liu Jingwen

Lotus didn't shelter from the rain,

There are branches of Ao Shuang in the chrysanthemum.

Good years must be remembered,

It's orange, orange and green.
