What are the taboos of ceiling feng shui?

(1) The ceiling can be made into a beam. Many modern decorations hide lamps on the ceiling as ceiling pressure heads! (2) No matter whether the lamp hidden in the ceiling is white or yellow, the white lamp tube is too cold and unlucky! Yellow tubes are better! (3) Don't put fans and lights on the ceiling! (4) Avoid festive flowers on the ceiling! (5) Avoid placing Tai Chi objects on the ceiling! (6) Don't decorate the ceiling with triangular and octagonal lights! (7) Don't hang a mirror on the ceiling! Don't dye the ceiling black, especially in shopping malls. Be careful!
