For a weak daymaster, Resource 印卩 is his Useful Ten Gods 喜用神. He has very strong Resource 印卩 and only Resource 印卩. Is this good?
Now let’s look at his BaZi.
Gui 癸 water born in Wu 午 month, a weak Gui 癸 water. His Useful Ten Gods is his Resources stars 印卩 which belong to metal. Metal is very strong.
Is this a good BaZi Four Pillars of Destiny?
A good BaZi, Useful and favorable Ten Gods 喜神 must have support and without major clash. His Useful Ten Gods is his Resources stars 印卩 which belong to metal and metal is strong but without any support from earth. Even with the Ji 己 earth inside Wu 午 fire, under the nature of the 5 elements, this particular earth is unable to support metal.
With only strong metal he will not be successful, in Chinese we referred this as 发不起 (not able to make it big).
At the same time, there is a major hidden issue. Look closer you will see there is a major clash between fire and metal, fire when become too strong could kill his Useful Ten Gods Resource metal. This will happen in his RenYin 壬寅 TaYun. Look for the year with strong fire. It can very bad 大凶.
