Mr. Wen Yiduo once used the word "light" to summarize the poetic characteristics of Luo Meng's integrity. How to understand this?

Meng Haoran spent the first half of his life mainly staying at home to study with relatives and adapting his own poems. Once lived in seclusion in Lumen Mountain. At the age of 40, you should travel to Beijing and return to Xiangyang. I made friends with Zhang Jiuling and Wang Wei when I was in Chang 'an. There is a poem title. After roaming in wuyue, the landscape is extremely poor, so as to solve the frustration of official career. He died of overeating. Meng Haoran's poems are mostly five-character short stories with limited themes. He writes more about landscapes, pastoral areas, seclusion and travel. Although it is not without cynicism, it is more of a poet's self-expression. He and Wang Wei are also called "Wang Meng", which is praised by Li Bai and Du Fu. There is Meng Haoran's collection. Although his poetry is not as broad as Wang's, it has unique artistic attainments, and it is the forerunner of the pastoral poetry school in Tang Dynasty after Tao Yuanming, Xie Lingyun and Xie Tiao. Meng Ke's poems are unpretentious, cordial and true, full of life breath and wonderful and complacent interest. Such as "Autumn Boasts Send Zhang Wu", "Passing the Old Village" and "Spring Dawn", which are light and elegant, integrated and elegant.
