The People's Post in Dunshou is the only calligraphy work handed down from generation to generation in Wei Guan. This post has basically lost its momentum, from which we can see the transition from Zhangcao to today's grass.
Wei Guan is the author of Mourning Instrument (Annals of Sui Shu Classics) and Notes on the Analects of Confucius (8 volumes).
The Complete Book of Jin also contains comments such as "Please discuss the table of removing clothes from false burial", "Please remove nine kinds of products and use soil to break the sparse", "Playing Shan Tao", "Playing for Zheng Mo's Third Division", "With a Book" and "With Wei Shu".
