Mo Chi is located in Linchuan County, Jiangxi Province. According to legend, it is the place where Wang Xizhi, a great calligrapher in the Eastern Jin Dynasty, washed his pens and inkstones. Ceng Gong admired Wang Xizhi's reputation and made a special trip to Linchuan to pay tribute to Mo Chi's remains in September of the eighth year of Li Qing (1048). Wang Sheng, a professor of Chinese studies (official name), asked him to write a note about "Mo Chi in Wang Youjun", so Ceng Gong wrote this famous essay "Mo Chi Ji" based on Wang Xizhi's anecdote.
For five thousand years, I once saw a saying that Wang Xizhi loved calligraphy and left several Mo Chi. In this way, you can understand these statements. It is not surprising to think that Wang Xizhi was an official in many places all his life, leaving a few Mo Chi. I hope it can solve the problem.
