If you are at home, I suggest you brush the back cover of the original wall first, and then brush the bottom, otherwise it will turn yellow. Cigarettes have fumigated the room, and there is no paint that is not afraid of smoke. You can try beige and light brown with similar colors, and wallpaper is even more undesirable. But the best way is to repaint the interior wall paint. Smoking less is good for yourself, the environment and your family.
