The name of Chengzhai style originated from Yang Wanli. Yang Wanli became a house, so it was called a house style. Yang Wanli, also known as "Mr. Chengzhai", was encouraged by the famous anti-gold star Zhang Jun with "sincere heart" and was personally given the word "Chengzhai" by Emperor Guangzong. This kind of "sincerity" not only shows his "sincerity" in learning, but also contains his "sincerity" to the country, which has profound implications. His poetry learned from Jiangxi Poetry School, and finally got rid of the shackles of predecessors, became a school of his own, and made high achievements. Chengzhai style is lively, natural and humorous. One of the factors that form the sincere style is that the poet projects his subjective feelings to the objective things to the greatest extent. The second factor is that Yang Wanli's poetic imagination is strange, but he does not use strange words, but uses simple and clear language and smooth composition. When approaching spoken English, his name is "Chengzhaiti".
Yang Wanli is sincere, so Yang Wanli's poems are called sincere style. He is good at drawing poetry materials from nature, inspiring poetry thoughts, and skillfully applying some fresh and interesting interests excavated from natural beauty to poetry creation, forming his own unique poetry style. The outstanding feature of "sincere fasting and rest" is that it takes living method as poetry, which is embodied in novel and strange conception, humorous style, popular and lively language and bright style. This is most obvious in Yang Wanli's natural landscape poems. He is particularly interested in nature. Mountains and rivers, blue sky and white clouds, moon, sun and stars, storms, rain and snow, birds, animals, insects, fish, flowers and trees are all included in his poems. He has a unique vision and mind, observes carefully, understands deeply and describes vividly.
