Does Tai Sui in geomantic omen refer to the position of wuhuang after entering the palace in a row? Or what? I've been reading that book for a long time and I can't understand it. T.T. Thanks.

Tai sui refers to one's own animal year, such as being born in the Year of the Monkey, so your Tai sui is a monkey. Tai sui is not necessarily bad, but it means moving more and changing more, such as breaking up in love or getting married, and the business is not getting better or going out of business directly. When we know it, we will add a good idea to make things develop in a good direction, which is the true intention of Feng Shui. The location where the lucky star or fleeting star-5 arrives every time is called wuhuang. If it is not shipped at 5, that is, it is not shipped at 5, then the location where 5 arrives is generally regarded as fierce, which is what we usually call wuhuang's evil spirit.
