From the visual aesthetic point of view, if the fence is too high, it will affect the villa's vision. Some walls are even as high as eaves or roofs, which look strange and give people a feeling of intolerance.
From the perspective of geomantic omen, it is very unlucky that the villa wall is too high, which will greatly weaken the airflow and fortune of the house.
Generally speaking, in order not to affect the lighting and ventilation, the height of the villa wall is about 1.5 meters.
