Are Liu Zhi and Liu Bocheng brothers?

Marshal Liu Bocheng, a senior general, and Liu Zhi, Chiang Kai-shek's "lucky general", lived together in the same place when they were young. In order to compete for the essence of local Feng Shui, Liu Bocheng and Liu Zhi launched a fierce battle between Yin and Yang. Because the Liu Zhi family accumulated too much evil, although the feng shui was good, it suffered a lot of losses. However, the Liu Bocheng family, who did many good deeds, absorbed the essence of the Liu Zhi family's feng shui. Liu Bocheng defeated Liu Zhi. In the Battle of Huaihai, Liu Zhi accepted the order and became the defeated general under Marshal Liu Bocheng. The two of them are combat rivals. Please accept if you are satisfied
