The failure of the wife star in the underground palace and the failure of the wife palace are two different things. The wife palace must be a Japanese branch, and the wife star can appear in other branches of the four pillars, which does not necessarily represent the wife. For example, Xin Guiyou and Jia Zi were defeated by Cai Jia. The son here refers to the position, rather than the general saying that Jia Zi was born in the month and Jia Mu was on the right in the north, but Jia Mu was not born in the north, and the north was the defeated place of Jia Mu. There are similarities and differences between numerology defeat and wind and water defeat.
