Another way is to put the fish tank in the porch position, which is not only used as a screen, but also has ornamental value, and can also make the gas field of the door come in twists and turns, killing two birds with one stone.
The third method is that you can put the fish tank in the brightest place in a room, so as to achieve indoor gas field balance. If you put the fish tank according to the first and second methods, but the light is too dim, it is still unlucky, not only will you not get rich, but you will also get sick. Therefore, if your fish tank has been placed in a place with poor light, you'd better set up a few small ever-burning lamps, which can improve it.
