Fu Yin can be good or bad. It depends on what are the involved ie. useful gods, hostile gods, their element and so on. Again you have to see all the 12 characters from 6 pillar as one whole picture. The 6 pillars are Year Month, Day, Hour, Ta Yun and Yearly.
Kong Wang is Shen Sha. You cannot based on the name to confirm it is bad. There are many saying like Kong Wang at year pillar, granddmother die early, or remarry, or leave hometown, or mother not treating son well, Kong Wang at month pillar, no sibling, or sibling cant be depended upon.and Time pillar with Kong Wang mostly stubborn, denotes no son. and so on. BUT if bad things are going to happen WHEN? You still have to fall back on the total interaction of the 6 pillars mentioned above to confirm whether it is bad or good.
If located in prosperous palace, not necessarily inauspicious; it can also be good. Also when Kong Wang encounters San Hui, San He, Liu He, it is no longer considered as Kong Wang. Do not believe too much on shen sha. The correct way is to look at the interaction among the elements, useful gods, hostile gods.... as one big picture.
Cheers.
