The earliest known sheshen was , a son of
Gonggong who was appointed as a god of the soil by
Zhuanxu. Tudigongs developed from land worship. Before
Chenghuangshen ("City Gods") became more prominent in China, land worship had a hierarchy of deities conforming strictly to social structure, in which the emperor, kings, dukes, officials, and common people were allowed to worship only the land gods within their command; the highest land deity was the
Houtu ("Queen of the Earth"). Ranked beneath
City Gods, the Tudigongs have been very popular among villagers as the grassroot deities since the 14th century during the
Ming dynasty. Some scholars speculate that this change came because of an imperial edict, because it is reported that the
Hongwu Emperor of the Ming dynasty was born in a Tudigong shrine. The image of a Tudigong is that of a simply clothed, smiling, white-bearded man. His wife, the Grandmother of the Village,
Tǔdìpó, looks like a normal old lady. In later generations, they became associated with
Wish trees. ==Variants==
