Dear Cecil,
Is it possible to apply 2 methods flying stars and 8
apirations at the same time, since there are some
conflicts between the 2, let say SW is unfavorable
"bad"for my kua 3, but good for flying stars and good
for 8 aspiration. So would you reconmend just folow one
or the other.
Thank you.

In the past, I had posted some actual case examples of real life Feng Shui done for clients. These samples are still available in the forum.

For example, please see attachment. It shows clearly how to integrate the Eight Mansions (rather than Aspirations) with the Flying Star Chart.
