First, don't look at the house at night. At night, the yin is heavy and it is easy to bump into bad things.
Second, don't go home alone, and don't be the first to enter the house. You should follow your family or an intermediary.
Third, the feeling of pregnant women is very important when looking at the house. Because the baby in the pregnant woman's stomach is "smart", if the gas field at home is not good, the baby will know that it will make trouble in the pregnant woman's stomach and make the pregnant woman uncomfortable. This situation shows that the house is not good. Better go out and stop watching.
