Where do you see that the cumulative CNY/BTC is more than cumulative USD/BTC?

Your link seems to show otherwise



Sunday afternoon/evening, when I logged my data into excel, china's volume was ~14.5k while big 3 volume was ~12.2k. For those that were asking above, china now has multiple large exchanges, with btcchina just being one of several. BTCkan is the best place to go for info, you just need to be able to read Chinese or use a translator or something.
