The door of the house faces a long corridor, which is called "backstab". This situation is not uncommon in modern apartment buildings. The corridor is like an arrow straight into the door, which will lead to no peace at home and repeated diseases and disasters. The solution to this is:
(1) Hanging bead curtain at the gate;
(2) Stick a mirror on the lintel;
(3) Place a pair of lions outside the door;
(4) Put the statue of Guan Gong outside the door.
Because the power of "backstabbing" is extraordinary, it is best to use a variety of solutions.
