What do girls represent with three pillows?

Three pillows represent a family of three, with prayers and children. 1。 When sleeping in the sky, the pillow should be placed on the neck, not on the shoulders or just on the back of the head. And put a pillow under your knees, which can reduce the pressure on your hips and waist and sleep more comfortably. 2。 When sleeping on your side, you should also put a pillow around your neck and a pillow at the knee between your legs, so that you won't feel tired. Just try it.
