After he was deported to Yongzhou, he wrote in the Preface to the Poems of Yugong Yixi: "Although the stream is not beneficial to the world, it is good at identifying all kinds of things, and it is so clear and beautiful that it resonates with gold and stone, which can make fools laugh and smile and adore, and they can't go away.......To sing the song of Yugong Yixi with a fool's speech, one would be at a loss and not go against it and return to the same place in the darkness. The first thing you need to do is to get your hands on some of the most popular products and services in the world."

Obviously, Liu Zongyuan is mocking himself and at the same time explaining the impotence of reality, which reflects his adherence to the rites and teachings; but at the same time, he also quoted the words of "Zhuangzi - in the宥",""莫我知", "Mo I know" emphasizes the unity of the "Xi" and "I", that is, the Taoist thought of the "unity of all", "the form of God with the forgetfulness of the". This is a borrowed objects to express their feelings, but the text can be seen in the back of this search for balance of thought on the deep influence of the scholar at that time.
