This issue is more complicated. On the surface, each person's birth time (or horoscope is more appropriate) is derived from the merits of the ancestors, but in fact it is mainly determined by one's previous life. Karma comes from karma. The feng shui of the ancestors' house can only be said to be a karmic environment. The merits of the ancestors and what you have created in your previous life are also the most important. For example, your karma in your previous life determines your destiny in this life. Reincarnation will naturally lead you to an environment that suits you. Of course, ancestors must continue to accumulate virtues from generation to generation, so that they will have the opportunity to obtain good Feng Shui and reproduce good-luck descendants. Otherwise, they will not be blessed. Haha, these questions are difficult to understand. The specific geography and public opinion of your question cannot be generalized. It can only be discussed one by one based on different geographies and different factors, such as mountains, rivers, orientation, etc. . .
