Put the eight diagrams and rice together in the grave.

Bagua array is a more subtle array derived from Taiji images. There is a saying: "Tai Chi gives birth to two instruments, two instruments give birth to four elephants, and four elephants give birth to gossip". As for gossip, the earliest saying is that Fuxi is the king of the world. He explored the mysteries of nature outward, examined his heart inward, and finally deduced Tai Chi gossip. But up to now, the most famous is the gossip in Zhouyi. According to Zuo Zhuan, Zhou used Zhouyi as a sorcerer's divination, and modern sorcerers used Zhouyi's tricks. People all say that Zhouyi is a book of divination, and Zhouyi is a book of immortals. Explain the magic of his divination Later, Taoism pushed the use of the Eight Diagrams in Zhouyi to a peak, and even evolved into a Eight Diagrams Array based on the Eight Diagrams, in which the Eight Diagrams are divided into eight meanings, namely, "dry as a horse, Kun as a cow, shock as a dragon, Xun as a chicken, Kan as a pheasant, Li as a pheasant, gen as a dog and changing sheep", which are eight totems respectively. Because the divination is a dragon, the dragon in the eight diagrams represents Yonghua wealth, while the other seven divinations are herbivores. Placing an eight-array map in front of the grave with rice means that the deceased can enjoy the treatment of rich clothes and ornaments in Yonghua below. The dutiful son should catch the rice sown by the Taoist priest with a cloth, which means picking up the rich rice.
