What are the feng shui taboos for TV background wall installation?

Not all TV walls are set with the whole wall as the background. In order to reflect the unity of the interior, some small-sized or fashionable homes will transform the TV wall into a partition low wall. The size of the low wall is generally not too high, about half a person to about one meter seven. However, in feng shui, it is not good to do so. Feng Shui believes that "the mountain is high and the water is low", but indoors, the wall is the mountain, the sofa represents the water, and the owner of the mountain manages the wealth. The mountain is not high, which is not good for people!
