zi moves to si looks so good, supporting parent line (wu). i also think the father would be better. somehow, the outcome wasn't good. probably it's because the month branch is xu, tomb of si & wu?
zi moved to si, si brought wu into tomb.
month zi, the time he passed away is also match with the hex.
saying about hospital's bad reputation, was there a malpractice? child line ussually is associated with medicine. unfortunately here this child line moves bringing the bad effect for parent line.
