The location of the indoor strong and weak current socket box is unreasonable. The distance between the strong and weak current boxes is too close. Generally， it is required to be 20cm， especially for the socket in the bedroom. The socket is covered by the wardrobe and bed during the later decoration of the owner， causing the owner dissatisfaction.
