1, the master said sit west and sit east, I agree. It should be calculated from the five elements of your industry. I am rich, so I want you to sit from west to east.
2. I don't understand the meaning of placing HongLing. The red five elements belong to fire, but they are golden, so I dare not say anything.
If there is a window in the back, there are two ways to solve it. One is to seal or partially seal the window, and the other is to use a high-back seat. The highest point of the seat is required to be higher than the head. (I used to say that the back window was bad because it used to be a bungalow, and it was easy to be attacked behind the window, which made people feel unsafe psychologically. Now it is the same, but there is basically no sneak attack, but the psychological feeling is not practical. )
My humble opinion is for reference only!
