Give a noun explanation to Feng Shui.

Qing Qianlong's Fu Zhi said: "There were hundreds of funerals, especially in Chenghai." Before burial, please ask Mr. Geography to explore the veins of earthworms, see the water potential of the air door, choose the place of holes, plan the pattern and start digging. Some people have stopped coffin for decades in search of "blessed land"; Some people open coffins and examine bones after ten or eight years of burial, and put them into clay pots (called golden pots, commonly known as fire golden urn) for reburial. Blessed are those who are buried as yellow bones and should be buried in the original cave again; Ivory is black and ominous, but "find another good city." In the old society, the countryside was full of houses and caves where coffins and gold cans were parked. In the 1930s, the Kuomintang government banned coffins, but it had little effect. Some people use coffins instead of coffins, that is, they temporarily find a burial place and wait for three years to move coffins or examine bones before burial. Some people build their own graves as soon as they are born. This is called building a living base. In order to "make feng shui", very rich people do not hesitate to spend huge sums of money, and middle-class families do their best.
