1. Avoid the top of the beam. Pressing the top of the beam is a taboo in Feng Shui. It will have an extremely negative impact on the owner's health and fortune, making people feel depressed. 2. Avoid overhead lights and ceiling fans. Having lights and ceiling fans above your head can make people feel insecure; and the air flow generated by ceiling fans can even change the feng shui of the room. 3. Do not hang fake flowers from the ceiling. Fake flowers are generally not recommended in home feng shui because they themselves do not have vitality. 4. Avoid placing Tai Chi objects on the ceiling. Some people think that Tai Chi can ward off evil spirits, so they make their own decisions and hang them on the roof. It should be noted that these professional tools for feng shui evil spirits must be used under the guidance of professionals to avoid unnecessary trouble. 5. Mirrors should not be hung on the roof. 6. The color of the ceiling should not be black to avoid the unlucky connotation of dark clouds.
