Does the oval ceiling in the living room affect Feng Shui?

The geomantic theory of living room ceiling does not seem to explain the taboo of oval ceiling, so there should be no argument that it is not conducive to geomantic omen and can be used for normal decoration. Ellipse is rich in geomantic omen, but where do the two main narrow circles face? If it is facing the entrance door, it has the taste of top wealth. Therefore, it is recommended to find a professional decoration designer to design and deal with it.
