Wang Xizhi's calligraphy is chic and elegant, and the font frame structure he wrote is very beautiful. Composition, structure and brushwork are all unique. Preface to Lanting is his masterpiece at the age of 33, which is called "the best running script in the world". The Preface to the Lanting Pavilion is elegant and free-spirited, revealing an elegant and heroic spirit. The lines between the lines are full of bones and muscles, full of flesh and blood, giving them their own personality, spiritual outlook and beautiful form. The heart knot is extremely changeable, not seeking justice, but focusing on the side. Symmetrical concession, stretching, convergence, ingenious arrangement, to achieve a diverse and unified artistic effect, the same word is full of changes.

In Wang Xizhi's running script, stroke is a transitional stroke and a relatively simple stroke, with few types and simple form. Its thickness, length and inclined screen are often coordinated according to the structure of words, and the pen collection is generally light, which has obvious echo relationship with the next pen.

Expose the front or hide the front to start writing, then draw a stroke downward, and then draw a stroke quickly to the right to form an intentional connection or connection with the next stroke. Length, size, and weight follow the words and cannot be artificial. For example, the words "hug, hug, land, although, see, meet, swim and be smooth" in the preface to Lanting Collection.
