In which book did the word "Feng Shui" first appear?

"Buried anger also. Qi dissipates by the wind, and the boundary water stops. The ancients gathered to make it last forever, and the deeds stopped, so it was called Feng Shui. " This passage comes from Guo Pu's Book of Burial in the Jin Dynasty. This is the first time that the word "geomantic omen" appeared in China ancient literature. Guo Pu concisely expounded the essence of Feng Shui theory: taking Yin and Yang as the foundation, taking Qi as the core, taking Tibetan wind as the condition, looking for an ideal burial environment as the starting point, and taking Yin Fu's children and grandchildren as the ultimate goal. Regarding how to define the quality of Feng Shui, Guo Pu's point of view is: "Getting water is the best, and Tibetan wind is the second." The main job of later feng shui masters is to find auspicious places where people can hide wind, get water and have vitality for burial or building houses, so as to facilitate people's development and reproduction. Funeral Book established a clear ideological system for Feng Shui and became a milestone in the development of Feng Shui theory.
