There is only one master clock in the living room, and no more than one wall clock in other rooms. If there are too many clocks at home, the peaceful atmosphere at home will become uncertain, and people in the house will often have changeable troubles.
The shape of the wall clock should be avoided.
The clock at home should be square and round. Try to avoid triangles, hexagons and octagons. These shapes of clocks will lead to disputes in the house, but round and square clocks are the most peaceful.
Not facing the door.
The clock can't be placed directly opposite the door. Although the wall clock should face the door, it can't be hung in the middle of the hall directly opposite the door. Because "bell" and "end" are homophonic, if someone opens the door and comes in, they will look up and see the bell (end), which may be associated with bad luck. Just hang it by the door.
