Houtu Temple is the place where emperors of past dynasties offered sacrifices to Houtu and the land gods. In the ancient custom of offering sacrifices to Houtu, Houtu gradually derived the titles of Land God and Houtu Emperor. In the Han dynasty, people called the land god "Mother Earth" or "The Earth". After the Tang Dynasty, according to the traditional concept of sunny days and cloudy days, the people created female land idols, which were called "land goddesses". Today's land gods, according to their different ministries, have different genders. For example, most of the land gods at home are men, while the land gods in charge of people at the entrance of the village are shaped into lovers, that is, the land Lord and the land woman. So the land god is the land god, and the tablet of the land god is the tablet of the land god. In ancient times, when burying the dead and building graves, a "land god" or a "blessing god" was placed on the left side of each grave, and the stone was erected, just like a small grave. This kind of stone monument is called "Houtu". In addition to the word "Houtu", some stone tablets erected by the Yin family dedicated to the land god will also be engraved with inscriptions. However, in ancient feudal society, the name of the memorial tablet of the land god often varies with the identity of the tomb owner. For example, the common people call it "Houtu", while the literati call it "Houtu God" or "Houtu God".
