What did ancient sages rely on for divination?

Methods such as plum blossom Yi Shu, six hexagrams prediction, Daoism, four pillars prediction, arrangement, three books, etc.

Roughly changing:

Turtle shell divination: Turtles are long-lived things. The ancients thought that they could communicate with gods, so they were used for divination and prediction. However, turtle shells cannot be reused and are not easy to obtain. A large number of predictions require a large number of tortoise shells. Where are so many turtle shells? So later, the fortune teller changed the tortoise shell into a map to predict divination.

Yarrow divination: The original plan was made of a kind of grass called yarrow. Fifty yarrow were in the hands of divination, and after many times, they came to divination again. This is the "trick" method. Some people also call it the large diffraction method, which can be used to predict any major event.

Bamboo chopsticks divination: yarrow was not so easy to obtain, and bamboo was later used as a planning strategy. From this word, we can see that the word "bamboo" stands for the purpose of bamboo, and the word "witch" below is the combination of the word "work". Workers are different from farmers. In ancient agricultural society, wizards held a high position and were the highest advisers of leaders. Unlike modern times, when it comes to witchcraft, people think of people who chase ghosts.

Copper coin divination: The ancients used bamboo divination to predict divination, which lasted for thousands of years. In the Han Dynasty, there was a man named Fang Jing who thought it was too complicated to use bamboo as a divination, and it was a waste of time to get a divination after eighteen changes. So he invented the method of divination with copper coins. Three coppers came out as soon as they were thrown. Throw it six times and it will be a hexagram. So his six-point prediction method continues to this day. Six-year forecast, also called Najia forecast, was the most popular forecasting method in ancient China.

The number of plum blossoms changes: Thousands of years later, a famous Yi-ology scholar named Shao Yong appeared in the Song Dynasty. It is said that he invented a divination prediction method without any tools, which is called plum blossom easy counting. This prediction method can start divination according to time, orientation and characters, and can get related divination without professional prediction tools, and then analyze and predict. The plum blossom easy number is also widely circulated, and it has become a block prediction method with the same reputation as the six-year prediction.
