If you watch a lot of Wang Xizhi's calligraphy, both his letters and his Preface to the Lanting Pavilion are generally "crooked".
Why write "crooked"? In terms of book theory, it is the pursuit of dynamic character, that is, "strangeness."
In the history of odd orthography, famous calligraphers rarely write the words correctly, because most people can do it after some training, while clever calligraphers correct the words askew, which is what we call odd orthography.
This tilt can give people a sense of movement, just like a steel bar lying flat on the ground without a sense of strength, but once it is bent or lifted, it will give people a sense of strength and potential. Ancient calligraphy, also known as "book potential", came from here.
