Whether it is from a scientific point of view or from a home feng shui point of view, a door needs to be built between the kitchen and the living room.
First, there is a door between the kitchen and the living room. You can close the door when cooking to prevent the walls and ceiling of the living room from being blackened by spilled oil smoke. In addition, if there are guests in the living room, the harmful physiological effects of oil fumes on the guests will also be avoided.
Secondly, from a Feng Shui perspective, the kitchen is the financial center of the home. If you often light a fire in the kitchen to cook, your family will be prosperous and your wealth will be prosperous. Wealth should be hidden rather than exposed, so try to isolate the kitchen and living room to prevent wealth from leaking out.
