Is it okay to use two cribs in the gatehouse of domestic houses?

Hello, it is ok to use two buttresses for the gatehouse of domestic houses.

Since ancient times, China has paid attention to the symmetry between the left and right, and the asymmetry affects the appearance, so the two buttresses are not only pleasing to the eye, but also very good from the perspective of geomantic omen.

Wall battlements are columnar structures protruding from the wall in the plane, which mainly play a role in strengthening the stability of the wall and can also be used as local load-bearing members.
