Zhoujiatai's(周家台)tombs bamboo slips of the Qin Dynasty has revealed the precious cases of the villagers' sacrifice to the god of agriculture in the Qin Dynasty. The bamboo slips mentions Xiannong(先农)and Nongfu(农夫)successively, causing differences in interpretation. The author argues that Nongfu is god of agriculture which took Tianjun(田畯)as the prototype, and coexisted with Xiannong. The practice of offering sacrifices to the two gods by villagers conforms to the ancient sacrificial tradition. In addition to using pig's ears to flatter the gods, the worshippers also use sympathetic witchcraft to drive the gods to help them get rich. This act of praying for self-interest and wealth accords with historical reality. The fact that the worshippers offered sacrifices to Xiannong alone reflected the impact of the worship of wealth on the traditional ancestor worship. The custom of offering private sacrifices to Xiannong in the Qin Dynasty continued in the Han Dynasty, which can be regarded as an important heritage of the Qin culture.
