It may be true, as we usually see, people like to make some mysterious renderings of people who have made great contributions or reputations in history. Later, there was a saying about Zeng Guofan's ancestral grave, saying that Zeng Guofan's ancestral grave inadvertently formed a very top feng shui, which was a golden rooster pecking rice. Therefore, the fate of Zeng Guofan's family was changed later.
After that, Zeng Guofan's family were all talented people. After 17 exam, Zeng Guofan's father finally passed the scholar, and finally Zeng Guofan even appeared as a perfect man in ancient and modern times. The evaluation of Zeng Guofan by later generations can be said to be very high. Although the period served by Zeng Guofan was a period of declining dynasties, his personal achievements were outstanding in any dynasty.
There is no such thing as feng shui. Any success comes from personal efforts, and it will never be plain sailing or something for nothing because of a piece of geomantic omen. It gives only a kind of psychological comfort at most, and the ultimate success depends on personal efforts.
