Usually the gas meter is in the cupboard, and the open kitchen gas meter is the same as the living room. The cupboard is out of breath, out of sight, out of mind, and now it's exposed, but it works in my heart. The open kitchen looks very foreign, suitable for families who don't cook very often, especially the general range hoods such as Hunan cuisine and Sichuan cuisine, which can't stop the smoke from drifting away and have gas risks. Therefore, the open kitchen is useless.
