At present, the backrest of the bed has its own shape. Therefore, using a headrest that helps me to use my eight-character or XiShen's five-element shape attributes will help my luck. On the other hand, if I use the bedside backrest, the shape attributes of the five elements are similar to the western gods and spirits in my eight characters, which will cause great harm to my luck. A serious situation will bring me bad luck.
On the form attribute of the five elements;
Gold has a circle, a semicircle and an arc.
Wood is rectangular.
Water is wavy.
A sharp fire has many water chestnuts.
The soil is square.
