Is "Hai Yan Jing Zhai" true?

1. The house should be cleaned before moving in. I believe many friends know that everyone pays more attention to cleaning the house. People will use coarse salt to clean houses, and the time for cleaning houses must be mastered, otherwise it will not work. Generally speaking, the time to clear the house depends on the specific situation. If the new house is to live in a clean room, it will take a day and a night to sweep away the coarse salt in the clean room. This can drive away cockroaches, mosquitoes, flies, mosquitoes and so on. In the house, and feng shui believes that it can exorcise evil spirits, life can be smooth after staying.

2. If you want to clean the house with coarse salt because there are unclean things at home after you check in, it usually takes a month to clean it. But when cleaning the house with coarse salt, don't sprinkle coarse salt all over the house, but put 30 grams of coarse salt in the cups at the four corners of the house, as well as in the kitchen, bathroom and door, which can improve the bad air in the house in one month. If you want to continue cleaning the house after a month, put on new coarse salt and scatter the replaced coarse salt on the outside land.
