It turned out that he invited a friend who knows a little about Feng Shui to see Feng Shui, but when his friend saw that the back plate of his bed was round, he said that the round one was gold, and "gold" was cold and should not be used in the house. Xiao Liu's friends are not wrong, but the circle has the function of "dissolving evil spirits", which is what most people call "unloading and killing", so everything can't be generalized.
It is lucky if the headrest is square or semi-circular, but it must be remembered that triangles cannot be used, because the headrest is in the shape of fire (the triangle in the five elements belongs to fire), and the owner's spirit will be worse and his temper will be more violent. Perhaps, people who like fire in the eight characters will have fewer problems using it to rest, but after all, there will be problems, so don't covet new headrests.
But coincidentally, Xiao Liu's life belongs to Jin, and he was born in summer. He shows weakness for Jin, so he likes Jin to help him. Therefore, the round backrest of the bed is very beneficial to him and will improve his luck.
