The development and prosperity of fortune telling in China has a profound social foundation. Ancient folk fortune-tellers infer their life's fate according to the eight characters. They correspond the year, month, day and hour of birth with heavenly stems and earthly branches, and each word is arranged in eight characters in turn, commonly known as eight-character fortune telling. Then they find out the five elements to which they belong, and then infer their fate and life span according to the theory of mutual generation and mutual resistance. This is the common understanding of fate by all living things, but it is assumed that there is an invisible force at work. Some people think that success or failure depends entirely on fate, so individuals don't have to work hard, just wait for good luck. I advise you: No matter how good the fertile land is, you should work hard, otherwise it will be overgrown with weeds.
