In the study of Bazi, one of the most common tool of reading is known as the 10 Gods. The 10 Gods represents certain relationship between others and us. Of course in the lingo of Bazi, us equates to the Day Master.
Hurting Officer is one of the most talked about in the reading of 10 Gods in Bazi. Hurting Officer is the classified as Output of the Day Master but with a Different Polarity. Output here simply means the element produced by the Day Master while polarity means Yin – Yang Polarity.
Thus if a person is born as a Jia 甲 Day Master, Hurting officer is represented by the element Ding 丁.
HURTING OFFICER (伤官)
Hurting officer (HO) is given the term is probably due to the reason this element hurts the Officer (官). Guan 官 in Chinese language usually means someone of authority or an executioner of a law or law enforcement officer or minister or in short a public officer etc. If you see the chart below, the Hurting Officer actually controls the Officer.
So if I use an example of a Ren Day Master, The HO will be represented by Yi wood. The Officer is by definition the element that controls the Day Master. Thus in this case it is the Earth element represented by Wu and Ji.
