Weak people can't breathe in mosquito nets, and some people feel suffocated in curtains, which is the result of curtains obstructing air circulation, and they move from sunny to cloudy, which is the origin of gathering Yin Qi. This is a scientific explanation of folk taboos.
In addition: in a circulating room, hanging mosquito nets can also gather gas, which is good for people with physical weakness. Therefore, when there are no mosquitoes, it is not appropriate to hang accounts, nor can we generalize.
Many folk taboos can be explained by science. There is no need to reject scientific solutions, and there is no need to think that folk taboos are superstitious and exclusive.
