Do you know who Zigu is?

Hua Fu (a divination method in China, also known as Fu Ji, Fu Luan, also known as Jiang Bi) originated in ancient China, and was first seen in Liu Yi Yuan in Liu Song Dynasty. At that time, people usually performed divination on the fifteenth day of the first month, relying on the beating of Zi Gu's idol. The summer season was also mentioned in Meng Qian's Bi Tan in the Song Dynasty. At that time, it was fashionable to welcome Ce Shen Zigu, and the date of coming to God was not limited to the 15th night of the first month.
