The astronomical calendar of Butang in Dongzhen 120 years old, and he is the third generation. When Cai Boli was a child, he didn't believe in Feng Shui either, and he thought that Feng Shui could not be trusted. Later, during the Japanese occupation period, when the situation was chaotic and he couldn't go to school well, his father suggested to him: Why don't you learn these things from me? Maybe you can use them to make a living in the future. So when I was 16 or 17, I studied Kanyu with my father.
Cai Boli practiced a lot, and found that good geomantic omen really has a good influence on people, and bad geomantic omen really causes diseases and difficulties, so he thought geomantic omen was valuable and began to study hard. The more he learned, the more he felt that China's astronomical calendar was profound, so he studied astronomical mathematics with Zhang, a famous mathematician in Guangzhou at that time, and with the former president of National Sun Yat-sen University and the head of the astronomy department. He got the true biography of his ancestors, and after painstaking research and long-term accumulation, he enriched and perfected the theory of "Star, Moon and Five Elements". Its theory has a wide influence in provinces, Hong Kong, Macao and at home and abroad.
