What is the theme of Wang Guozhen's appreciation of I Know? Thank you.

Today, when cynicism and lower-body doctrine are rampant, rereading Wang Guozhen's poems can be said to wash the soul, cultivate sentiment and make people realize in ignorance. Wang Guozhen's poems never deliberately pursue the beauty of words, and never passively fall into the so-called main theme. But I use the simplest language, the most sincere emotion and the most thorough understanding to tell you the details of life, which is touching and touching. This is Wang Guozhen, who reasoned with poetry and taught Taoism with poetry.
