It is used to observe the health or body condition of the questioner.
The relation between this palace and the fourteen stars can be divided into three groups.
(1) Absolutely good – only Treasury Star (Tian Fu)
(2) When the score is in plus sign, then it is good; yet when the score is in minus sign, then it is not good -
Emperor Star (Zi Wei), Mercy Star (Tian Ji), Sun (Tai Yang), Lucky Star (Tian Tong), Moon (Tai Yin), Minister Star (Tian Xiang) and Blessing Star (Tian Liang)
(3) Absolutely bad - Finance Star (Wu Qu), Wicked Star (Lian Chen), Flirting Star (Tan Lang), Gloomy Star (Ju Men), Power Star (Chi-Sha), and Ruinous Star (Po Jun)
So, by observing these groups of stars in the Health Palace, you can know the body condition of the questioner.
As to the absolutely good or the stars with plus sign, the one has good health and can live peacefully.
In the contrary, the absolutely bad or the stars with minus sign, the one must be tormented by disease for all the life.
