Why can't the compass be kept at home?

The compass can be kept at home. Our common compass (commonly known as high-precision compass) is just a tool for ordinary people, just like the compass in a mobile phone. If your compass is illuminated by the master and has aura, then you should cherish this treasure. People can't put the compass sideways on the ground at will. Wrap it in red silk and protect it. It will bring you good luck, so you can leave it at home. Just pay attention to the preservation method.
