This is superstition. In the ancient history of China, there has always been the concept of destiny and the theory of the induction between man and nature. The political value of this theory lies in demonstrating the legitimacy of imperial rule and educating people to obey God's will and accept their own destiny, so everything is doomed and they should be content with the status quo.
As the saying goes, "Man proposes, God disposes", which also means the spirit of Ah Q.
"God forbid", the positive and optimistic explanation is that everything can be done as long as you try your best, and nothing should be forced.
