First: If I can't change the direction of the door, the best way is to set an opaque porch or screen between the two doors, which is higher than one meter. In modern families, there are many beautiful screens. This is a relatively simple method, but it will make the space between the master bedroom and the second bedroom smaller and slightly crowded.
Second: hang feng shui ornaments. You can put some auspicious ornaments in the master bedroom and the second bedroom, such as Chinese knots, rich peony pictures, or amethyst bead curtains, which are very simple to operate and can also decorate the bedroom.
The third way: don't open two doors at the same time, to prevent the air flow in two bedrooms, and the indoor gas field is in a relatively static state. This method is simple, but it may bring inconvenience.
The door-to-door phenomenon in the master bedroom and the second bedroom often occurs at home. If this happens in your home, you can choose the most suitable method to solve it.
