The whole word euphemistically expresses the author's love for flowers, fully embodies the author's love for nature and spring, and also expresses the author's inner anguish.
On the night of spring, nature experienced a storm. The poet foresaw that the flowers and trees in the garden must be lush with green leaves and withered flowers. So, the next morning, she eagerly asked the "confined person" about the outdoor changes, but the careless "confined person" replied "Haitang is still there." In this regard, the poet can't help but use two "know whether" and one "should" to correct his careless observation and wrong answer. The phrase "green and fat and red and thin" vividly reflects the author's regret that spring has gone and spring has come.
Although the length is short, it is implicit and meaningful. With the scenery as the background, it is exquisite, delicate and ingenious, vividly portraying the psychological feelings of the characters, promoting the development of the meaning of words through dialogue, ups and downs, and extremely vivid, showing the author's profound artistic foundation. Later generations spoke highly of this word, especially the phrase "green and fat, red and thin", which was highly praised by scholars of all ages.
