What rhetorical devices did Zhang Lei use?

Correct me, the title is incomplete, but what rhetorical devices did Zhang Lei feel during the Spring Festival Gala?

The second combination of double rhetoric in this poem shows the beauty of late spring. The third part adopts the form of questions and answers. On the surface, it is talking about the weather, but in fact it is expressing inner loneliness.

The original poem is:

In Luochuan, in March, the snipe was singing and swimming in the air, which was not shocking at all.

The velvet grass is soft, and Xiao Yang's flowers are light.

Where the clouds spend the end of the day, it is better to break the spring sunshine with light rain.

Guests from the south of the Yangtze River have increased their thoughts and are looking forward to a healthy life in Tingzhou.

Zhang Lei, whose real name is Qian Wen and whose name is Keshan, is called Mr. Wan Qiu and Zhang Youshi. Because of its huge shape and brawniness, people also call it "Fat Fairy". He was born in the Northern Song Dynasty to the first year of Harmony (1054) and died in Zhenghe four years (1114) at the age of 6 1 year. He is a Jinshi in Xining, Song Shenzong. He has always been the master book, writer and historian of Linhuai. At the beginning of Zhezong Shaoshengri, he met Runzhou with Zhilongge. At the beginning of Song Huizong, he was called Taichang Shao Qing. One of the four bachelor's degrees in Sumen. Among the "Four Bachelor of Su Men" (Qin Guan, Huang Tingjian, Zhang Lei, Chao), the writer who died the latest and was deeply influenced by Tang Yin. On poetry, Bai Juyi and Zhang Ji are simple and comfortable, not polished, but often sloppy; Its words are rarely circulated, its language is fragrant and graceful, and its style is similar to that of Liu Yong and Qin Guan. His representative works include Youth Journey and Romantic Teenager. "Journey to Youth" is about the feelings of boudoir, and the modality of shy girls is vivid on the paper, which makes people envy and feel distressed. That kind of warmth is really a bit "too strong to melt away". He is the author of Keshan Collection and Wanqiu Collection. There are poems of Keshan and Zhao Wanli. Later, he was accused of being a member of the Yuan You Party, was demoted several times, and lived in Chen Zhou in his later years.
