What kinds of prophecies were there in ancient times? How accurate is the prediction?

What are the ancient prophecies? There are mainly divination, astrology and astrology. Is the prediction really accurate? Whether it is allowed or not, everyone has different opinions. I think these ancient predictions of China are quite accurate. To give a simple example, Yuan Tiangang calculated the TuiBei diagram according to the records at that time, and even calculated the fate of the next two thousand years. Yi Gua: The Book of Changes, which we often talk about, contains sixty-four hexagrams, which can be used to calculate the development and quality of things according to the chapters and hexagrams.

Physiognomy: As a common test method now, physiognomy is also what we often say. This is an early test method, which judges the quality and progress of things according to people's faces, faces, sounds and colors.

Astrology: According to astronomy, we mainly use astronomical knowledge to judge and judge the quality and progress of things.

Everyone has different views on this thing, maybe it's a coincidence, maybe it's a real skill, and everyone has their own views. This superstitious thing must be resolutely banned, but it is still interesting for cultural inheritance. Take its essence and discard its dross, which is called cultural inheritance!
