The answer downstairs is quite good. Bricklaying standard is 5 cm, and the current height is generally 2750cm. After the ground is finished, it should be around 2700cm. I don't know whether you mean somewhere or the whole house. If it is the ceiling of an aisle or a guest restaurant, it is possible, because the overall effect should be considered when the ceiling is hung (for example, there are girders or central air conditioners, in order to decorate the beams or ensure the position of the air outlet of the central air conditioner, it may be hung down by 30 cm, so the height of this place may be only 2530cm. However, if the height of a room without a ceiling is only 2530cm, it is a bit low. Too low ceiling in furniture geomantic omen is a taboo. It is said that Mount Tai is not conducive to the master's fortune. I suggest you check the national and local commercial housing construction standards and norms.
Thank you, hope to adopt.
