Can you see this from the image of the natal chart?
It's in the year, month and day pillars. Wu in the year stem and inside the year branch, geng in the month stem and inside the month branch, while yi is in the day stem and in the day branch.
Technical wise, this chart is a fake follower chart. So, his negative stars are the water and wood stars. This boy is from a very rich background as his wealth stars are strongly rooted in the year pillar.
However, his present ren-xu LP is an unfavourable one because the negative ren water is protruding. He told me that he had many operations on his liver when he was 14 years old. The yi wood DM being sandwiched by the xin and geng metal gives us the image of the operations.
