This is simple. The so-called Yongshen, of course, refers to the fortune-telling. It should be auspicious.
The noon fire is the fortune star and the god of use. You must have money. If you hide it at noon, you will make money silently. If wealth is used as a wife, the wife will be beautiful and can help her husband.
Fire is the wife, fire is the host, and Yan is the superior. If you are happy with your wife, you must be upright and generous, well-informed, outgoing and lively, and have a good demeanor.
In short, the wife should be in the element of fire.
