It expresses the host's yearning for freedom, saying that all scholars are equal and stand at the window, as if they are freely shuttling between the moon and the clouds, which shows the poet's yearning for free life. This sentence comes from Preface to Lanting Collection.

Preface to Lanting Collection was written in China Jin Dynasty (AD 353). Wang Xizhi, a book sage, wrote books and made friends at the foot of Zhu Lan Mountain in Shaoxing, Zhejiang Province, and wrote "the best running script in the world", also known as Preface to Lanting, Preface to He Lin, Preface to Lanting March 3, etc.

In April 353 A.D. (on the third day of March, the ninth year of Jin Yong, 1667 years ago), Wang Xizhi, who was then the folk history of Huiji, and 41 people, including friends Xie An and Sun Chuo, drank wine and wrote poems in Ji Ya, Lanting, Huiji, Yin Shan. Wang Xizhi compiled these poems into an episode, made a preface, described the swimming event, and expressed the inner feelings caused by it. This preface is Preface to Lanting Collection. And wrote "Preface to Lanting Collection".

Emperor Taizong attached great importance to him. He once wrote a biography of Wang Xizhi in the Book of Jin, praising him as "perfect".

Although Preface to Lanting is not as good as Wang Shu's cursive script, as an elegant, leisurely and chic style of the times, no one can surpass it and accompany it. That kind of elegant layout, elegant style, changeable brushwork, and easy borrowing make later learners feel that they are facing an ordinary and mysterious tower, which is often impossible to enter. As long as we look at the richness of their pens, there are all kinds of wonderful changes, such as hidden front, weighing ornaments, hanging pens to return to the front, tying lines, reflecting belts, turning from square to circle and from circle to square. This is also the permanent artistic charm of Lanting Preface. The so-called "non-stimulation, non-stimulation, self-discipline" (in the words of Tang Sun Guoting) should be the most appropriate evaluation of the gods in the Preface to Lanting.

The calligraphy of Preface to Lanting conforms to the most basic aesthetic view of traditional calligraphy: "The style is not flashy, the quality is not wild, and the style is gentle." His brushwork combines rigidity with softness, his lines are flexible, his stippling is concise, his book style is based on dispersion, and he has the aesthetic feeling of respect, concession and comparison, which has become a model of "the beauty of neutralization". Appreciating the Preface to Lanting will give you an extraordinary artistic enjoyment.
