How to understand the fortune-telling phenomenon in the Book of Changes dialectically?

In short:

1, fortune telling is a skill. Based on the numerology derived from Yin-Yang and Five Elements in Yijing, it is one of the applications of Chinese studies with theory and long-term practice (commonly known as Shu Shu).

2. The explanation of numerology is scientific, accurate from the statistical point of view, and has a certain predictive and guiding role in life. However, due to historical reasons, it inevitably contains unreasonable and even vague things.

3. Fortune-telling is actually a service provided by some professionals with certain fortune-telling knowledge for those who need consultation. It is really common to ask questions on their own initiative.

Speaking of which, it's quite complicated. Fortune teller is the key, which can be roughly divided into three categories: knowledgeable, passable and passable. The first two are level issues, and the last one is moral issues. However, it is undeniable that at present, the latter accounts for a large proportion and has an increasing trend, which is worth worrying about. In other words, in the fortune-telling industry (let's define an industry), both technology and professional ethics are obviously mixed.

4. Fortune-telling will exist for a long time. Among them, it is determined by the reasonable factors of fortune telling itself, the needs of a large number of practitioners, enthusiasts and the public. Although there are many ugliness behind this phenomenon, the philosopher's saying that "what exists is reasonable" has been circulating for at least 2000 years, and there must be some reason for it. This is the advanced prediction function of fortune telling, and the psychic communication function that fortune tellers attach to the calculated is difficult for outsiders to achieve-it is undeniable that this aspect is very close to modern psychology.
