Being an international student is tough. Being a chinese international student is some next level shizzle. I've heard that one of the biggest fears faculty/grad comm have about chinese international students is that they're real good at taking tests (some think there's cheating involved) but when the students come down for interviews, the can't speak well, and some cant write well either. Unfortunately for you (and to a lesser extent, me, also an international student) your AWA scores kinda reflect that. So i'd recommend that you get your SOP checked and vet by someone from america (having brought up in a british system, we spell everything 'wrong' ?). Make sure it's a killer SOP and get your recommenders to cover your AWA score. To reflect that you can speak and write well, maybe just not under pressure; but you can definitely articulate your ideas in speech and writing. Hope this helps!
(P.S. I assumed you're chinese from the chen in your handle. If i'm wrong, you can disregard the chinese part but the rest prob apply hahahaha)
