The name of Dongguan is related to Wancao. Lv Xiang, the earliest extant author of Dongguan County Annals, was a scholar in the seventh year of Ming Zhengtong (1442). His poem "Wan Cao" is well known to later generations: Wan Cao is ugly in color; This land is suitable for the eastern part of the South China Sea; Sorry about the grass and its color; Don't be sloppy, be suitable for the seat; Provide proper food for the people; The name of this city is actually Wei Yi. The poem tells the origin of the name "Dongguan", which is a document written by famous people about the name of Dongguan and Wancao.
