What is the significance of the case of Dragon Tiger Beidou in Puyang, Henan Province?

In many ancient tombs in China, there are patterns of dragon and tiger, the most representative of which is the dragon and tiger made of shells in Puyang, Henan. This shows that the tomb owner was very keen on Taoist health preservation before his death and had a thorough understanding of Taoist health preservation knowledge. Dragon Tiger means to bring down Dragon Tiger, Beidou means to practice time, and the leg bone of Taoist boy is placed in the position of bucket handle. Explain that this Taoist boy is responsible for the schedule of the tomb owner. Because the ancients used the Big Dipper to judge the timing of the night. There is a passage that fits this tomb format very well, which can fully explain the meaning of this tomb format. As the Taoist saying goes, Beidou moves south, and the traffic in Shenhe Canal is endless. The driver of the river is sleeping and will still pick up the cat tomorrow. The dragon, white tiger and big dipper in this tomb try to show that the owner of the tomb is not dead. Just sleeping after practice. It can also be understood that the soul of the tomb owner is practicing, and people can practice to become immortals after death. It's called ghost fairy. If you pay attention to The Journey to the West, in the section of True and False Monkey King, the Buddha said that there are five kinds of immortals: immortal, immortal, immortal and ghost fairy.
