That would be really helpful man, there's no one I know here play Chin.. None!
Although I must say I haven't got the chance to try him out myself, so I have no idea how to read him.
but yeah, I'm interested to hear some advice from you on how to play him. 
-Chin's overhead can be interrupted easily, you can do d.A and it'll stop the move.
-After blocking the overhead, any one frame grabs can punish him before I can get my Quickie Punches (the two quick hits)
-You can always roll backwards right after you block the overhead before my Quickie Punches come out.
-A quick reversal like Ryo's DP, Kula's DP can also hit me before my Quickie Punches come out.
-Ex counter although counters high and low has a very short window and you can hit him after it comes out as he walks backwards.
-B counter (looks the same as the D one) counters high hits and specials, it stays out longer so becareful, just hit me low if I go for it.
-D counter hits low but I seldom go for it as it's hard to follow up after it (unless I'm near the corner) without blowing a stock.
-Like GCCDs, if you do a deep jump attack, my B counter will activate but you'll land in time and can block my follow up to the counter (he does a s.D).
-Overall, just learn to bait my counters.
-My rotation punches (the one where he rolls across the ground) is vulnerable to low hits so you can d.B me out of it as I approach you, just be careful as my Ex version is invincible low.
-When I drink, I dish out more damage but I also take more damage as well, so rip a big combo whenever you get a chance when I'm pink.
I feel nakedly exposed now.
