How should I put the wardrobe and computer in a 3-meter by 3-meter bedroom without taking up space?

Put the head of the bed facing north and place it next to the window. The space can be fully utilized. The window provides good lighting and fresh air. It is also good for Feng Shui! In the remaining space, two sofa chairs and a coffee table can be placed on the north side, and a TV, computer, etc. can be placed on the south side! Opposite the door can be placed a clothes rack, wardrobe or other storage items. This is a perfect dormitory!
