The point is that the living room is too small and too far back.
Others, such as the door facing the corridor and the lying door facing it, are all pediatrics and will not affect the overall situation.
Suggestion: tear down the existing kitchen and connect it to make a living room.
The kitchen is changed into a dining room, and the balcony is used when the area is small.
The lying door is hung with curtains and Chinese knots.
For shorter indoor corridors, there is no problem getting started. There's something wrong with the corridor outside.
