A, from the perspective of feng shui, the pond in the yard, pay attention to a lot, and fierce:
In addition to the "crying pool" (two ponds were built in front of the house, which looked like crying characters) and "blood basin in the mirror" (the pond was opened in front of the house) mentioned in Ten Books of Yang Zhai and Eight Houses Mirror, other life books also discussed the fierceness of the ponds in the courtyard. Shao Weihua concluded: "The house is big, the pond is small, the man is lonely, and the woman is dead. The goose head is shaped like a pond, which is absurd to both men and women. The house is small and the pool is big, and the money is scattered. The pond is like a corpse, and people are dying. The pond in front of the door is very big, but its life span is not long. The pond behind the house is big, and there are young casualties. The front pond is straight and dies young when you go out. The back pool is narrow and the family is few. Zuo Tang grew up straight and fled his hometown. Without the right pool and the left pool, there will be widows. I died in vain before and after the pond. Zuotang road is straight, shaped like a gun elbow, and children and grandchildren are at the mercy of others. The big pond and the small pond are lonely and miserable. Go up to the pool and go down to the pool, and fewer children will die. A hook rolled in the right ditch, and the sputum fan was stolen by a thief. The pool is half-moon, and the family will be separated. Just behind the front pool, fewer people died and more widows. The water pavilion rises from the pond, and the fierce man calls for disaster. Outside the pool, loneliness hurts your eyes more. There are mountains in the pond, and life is a matter of concern. The water in the pond is like yellow mud, and my eyes are in a coma. There is a small pond behind the house, and the decoction is made at home. After Tang Qian reformed, his parents would die young. The water pumped from the pool in the hall (the water pumped from the pool in front of the hall) often smells like crying. Open a new pond in front of the door, and you will definitely play. One end of anterior cistern is shallow, the other end is deep, and shallow depth is abortion. The front pool is wide at one end and narrow at the other, and the small tail has always been a house. The gate pond looks like a gourd, and there are many orphans in the first generation. The pond triangle has many tongues. If Don's head looks like a corpse, he will be convicted of rape and drowning. The house is by the pond, and the water is boundless. Three generations have lost the other shore. The two ponds in front of the door are close to the house, recruiting adopted sons and adopted wives. The two ponds in front of the door are big, forming a blessing. "
Secondly, from the perspective of real life, the disadvantages of building a pond in a hospital outweigh the advantages: the main reason is that if the pond water cannot be changed frequently (easier said than done), it will definitely become stagnant water, stink and breed a large number of mosquitoes.
Third, if it must be opened, it must be: 1, and the bottom of the pond and its surroundings must be hardened; 2. Set a faucet beside the pond to ensure convenient water change; 3. Be sure to set a drainage pipe at the bottom of the pond.
