Wei Qianli was a famous character in the Republic of China. Why didn't he even see his own character? Can you explain that the study of eight characters is a fool?

Wei Qianli was an eight-character fortune teller in the Republic of China. He devoted his life to the numerology research and exploration of all sentient beings. Like a doctor, he seldom pays attention to his own life. He can cure everyone's diseases, but it is difficult to cure himself. This is also a fact. It can't be said that he can't cure the disease, just fooling others. It can't be said that everyone died in the end, which means that the science of medicine is a fool! It is true that there are doctors who can cure their own diseases; In the same way, fortune tellers can calculate their own lives. In the era of Master Wei Qianli, when the army was fighting, the people were in dire straits, and the people were not poor ... nor were horoscope fortune tellers. It is wise for future generations to stand on the shoulders of predecessors, and it is sincere and fair to understand the inaccuracies of predecessors.
