First of all, I want to know if the beam is in the middle of the living room. Secondly, how wide the beam is and how much it hangs down! If it is not normal to hang it under the beam, it is to hang the top flat and wrap the beam! This should be based on the height of your home. If you hang a lot, you can only use the decorative weakening method (my name is (* _ _ *) hee hee), for example, wrap wood skin on both sides of the beam to make a fake beam, and weaken the beam through symmetry, decoration and color to achieve beautiful results. Give you a picture reference, hope to adopt!
