Why is the TV in the corner and the TV signal is good?

This feng shui is irrelevant, don't be so superstitious! Put it in the corner, the TV signal is good because the TV will produce a certain magnetic field when it works normally. Being near the corner is equivalent to amplifying the receiving antenna of the TV. Of course, the signal will be better, and this only refers to those wireless TVs. It makes no difference where the cable TV is put. The key is to look at the signal strength of the cable terminal.
