I have a theory as to where the Shenmue story may be going that might interest some of you. This might have been said before but, here goes anyway. Is it possible that in order for Ryo to get to Lan Di he will have to get one of the leaders of the Chi You Men to help him out. From everything I've heard it would appear that all 4 leaders each guard some sort of entrance or geographic location of some sort. Also juging by the lttle white yang stone that xiuying gives Ryo it would be safe to assume that Ziming is going to be the one to help and that little stone is going to convince him to do so.
Is it also possible that Ryo and Ziming have already met. Could Master Baihu in fact be Ziming... maybe. The only problem I have with this theory is that if Baihu is Ziming and in fact one of the four leaders of the Chi You Men then how the heck did Ryo beat him. Either he is very careless and underestimated Ryo or... He let him win on purpose. let's assume the latter but what would he possibly gain by doing this. Maybe it was a test to see how stong Ryo is, for what reason I am not yet certain. A quick side note: in all flash backs Ryo has the same hair cut as a child, so does xiuying (kind of) if you compare Child Ziming to Baihu I see the same similarity (or maybe I'm just looking too hard)
I was also thinking does the tiger on Ryo's back hold some sort of significance. Is Ryo going to replace Ziming as one of the four leaders of the Chi You Men. It seems his father had some sort of connection the them. Maybe his father was once one of the four leaders himself. It would explain why Lan Di didn't kill Ryo on that rooftop in Kowloon when he had the chance. Maybe he needs him to fulfill some kind of prophecy.
And finally let's assume that the four leaders of the Chi You Men are going to be replaced. Ryo Would be the Tiger, Sha Hua phenix and either Ziming or xiuying would be Dragon and Serpent it's hard to say who would be which. All four of these characters have no ties to stop them from doing so.
Thoughts anyone?
