Why does "clearing the capsule" become synonymous with Feng Shui?

Because of Guo Pu, a native of the Eastern Jin Dynasty, Green Capsule can be synonymous with "Feng Shui" or "Kanyu". Guo Pu (276-324), a native of wenxi county, Hedong, was the son of Jianping, the satrap of the Western Jin Dynasty. He was a famous scholar in the Eastern Jin Dynasty, not only a litterateur and an exegetist, but also a master of Taoism and the founder of poems about immortals. He is also the originator of Feng Shui in China, and his books have buried the classics. At the end of the Western Jin Dynasty, the war was about to start, and Guo Pu fled the south of the Yangtze River. At the end of the Western Jin Dynasty, Wang Dunren joined the army as a clerk. In 324, Dun wanted to rebel and ordered him to divine. He was killed at the age of 49. Jin Mingdi built the "Guo Gongdun" monument for Guo Pu on the bank of Xuanwu Lake. Guo Pu is the Big Dipper of Mount Tai in the geomantic world. Feng Shui: Qi rides the wind to disperse, and the boundary water stops. The owner of the mountain has decided, and the water is the owner of the wealth. The five elements of feng shui fish pond belong to the wealth and wisdom of water management. His major works include Tibetan Scriptures, Poems of Wandering Immortals, Fu Jiang, etc. It is said that Guo Pu got the nine volumes of the book in Huang Shigong's green bag, thus gaining insight into the five elements, astronomy and divination, and wrote the classic book Burial Book. This book is comprehensive and profound. "There are five stars in the sky, five elements on the ground, stars in the sky, mountains and rivers on the ground, qi on the ground, beautiful scenery in the sky, and the discipline of establishing people is extremely purple." At present, Huang Shigong's Qingnangjing is divided into three volumes, and the full text is only 4 10.

Qingnangjing is a biography of Huang Shigong at the end of Qin Dynasty and the beginning of Han Dynasty, and it is the first record of Feng Shui in the history of China. Under the system of China's ancient philosophy, Neijing of Qing Dynasty established a specific philosophical thought and theoretical system of "Feng Shui".

Although Qingnangjing has only 400 words, it is profound, concise, straightforward and not mysterious, but it reveals Luan Tou's method of regulating qi and feng shui, laying the foundation stone for the development of feng shui.
