How to decorate the 8-meter-long living room?

I agree with upstairs that the north wall near the dining room door is used as a decorative wall near the dining table, about1.8m.. There is a sofa in the east (that is, under the north window), and the wall between the study and the east bedroom door is the TV wall. If there is no beam on the top surface, it is also recommended to level the top, scrape putty and brush latex paint.

The important opinion is that you should make a screen at the entrance of the room, facing north and south, so that the entrance door and bathroom door should not go straight, otherwise it is a big taboo. Make a shoe cabinet against the wall on the south side of the screen. If the door of the east bedroom is not properly adjusted, it may be moved to the west to ensure that the wall in the east is deep enough and the screen can reach the door.

If you need a detailed design, please give me the size and I will draw a CAD drawing for you.
