According to Feng Shui, is it okay to pull a protective net around the house?

From the perspective of geomantic omen, can you pull a protective net around the house? The answer is: ordinary residential buildings do not need to be fenced, and houses with special needs, such as prisons, military restricted areas, important material reserves, custody institutions and secret institutions, are clearly stipulated by the state, which is another matter. There are always many things, so we should think from many angles: first, from the perspective of gains and losses, pulling and protecting the power grid can certainly play a necessary role in security protection, but there are also dangers and risks, and the possibility of serious damage is certain. For the average person, the ability to bear this kind of injury is limited. At the same time, a protective power grid has been built around houses with no special purpose. The law does not explicitly stipulate that it is ok to pull a protective power grid around the house, nor does it explicitly stipulate that it is not allowed to pull a protective power grid around the house. In the event of a dangerous accident, it will become that many people make strength, dogs kill wolves, and the public is right and the old woman is right. The result of evolution is that power is right. Second, from a psychological point of view, pulling to protect the power grid can certainly play a necessary protective role, but it may also lead to disaster and much ado about nothing. Originally an ordinary house, some people mistakenly thought it was a land of wealth and became the target of criminal attacks. If others are the target of choice, what can the protective power grid resist? Therefore, it is better for ordinary people to be human with their tails between their legs, and it is less troublesome not to protect the power grid. Only consider feng shui, first of all, we should start with common sense thinking and seek common sense. If common sense can't find a reasonable answer, seek to meet psychological needs from the perspective of geomantic omen.
