What are the solutions to the lack of sunlight in the living room?

Whether the living room is dark or bright is a personal issue, not a Feng Shui issue. When there is insufficient sunlight, you can use brightly colored decorations or wallpaper or wall paint to brighten the visual experience, or install some small lights. If there is no sunlight, you can only use lights to make up for it, and adjust the brightness to your own. I feel relatively comfortable.
