This is a weak geng day master and it harnesses wealth on its self stars. So, the protruding xin metal in the month stem represents his wealth. He was born in the si month and si is part of the si-you-chou metal frame. The metal star inside si is geng. So, his HVN star is xin. Just like the previous case, his HVN star also represents his wealth star. Bingo!
