Why did ancient people choose to use tortoise shells for divination? Is there any reason here?

China's divination culture has a long history, with thousands of years of history and culture. Ancient people still could not compete with nature. At that time, people were in awe of everything in nature. The flags of ancient people were all symbolized by animals. The Queen Mother of the West is a very powerful figure in the hearts of ancient people, an ancient god beast. However, it has always been deified by the ancients. Some people say that the Queen Mother of the West is a snake, while others say that the Queen Mother of the West is not a person.

In ancient times, dragons were regarded as kings and the most sacred things. The clothes worn by the emperor are printed with dragon balls, and the clothes worn by the queen are printed with phoenix patterns. All animals have many meanings, for example, Erlang God has a dog, Chang 'e's sister has a little jade rabbit, and Marshal becomes a pig, which represents the lust and laziness of the pig. the Monkey King is, which represents his rashness and irrationality, and Bai represents his efforts.

Turtles were also regarded as sacred species in ancient times. The tortoise used to be called Xuanwu in comics, yes, Xuanwu, Qinglong, White Tiger, Suzaku and Huanglong. Turtles also represent longevity, so whenever the elderly celebrate their longevity, they will be given turtles to wish them longevity. Another reason is that the lines on the tortoise are very strange. Everyone knows that turtles have a hard shell, but the lines on this shell are different.

These lines on the tortoise just correspond to the sixty-four hexagrams in Zhouyi. Although the tortoise was slow, it won the race between the tortoise and the rabbit. The tortoise has the spirit of modesty and persistence. The wisdom of the ancients discovered these strange things. These animals may have condensed the efforts of the ancients for thousands of years. People use turtles for divination. In Journey to the West, four people crossed the river with turtles. The turtle itself is an unparalleled ancient sacred object.
