I can read Chinese, and I can confidently say LIULIANGKUANG is very, very different from Bitcloud. There are only similar in the idea of "reward by bandwidth".

First, it's a project serves a COMMERCIAL company, namely 深圳市快播科技有限公司 or Shenzhen QVOD Technology Co.
Second, all bandwidth in the system are facilitated by QVOD and QVOD only. QVOD is also the name of the video player of the company,
and with the important feature of P2P video sharing. And the most famous adult-video-spreading software in China, it's simply known as the "Adult Video Player".
Third, the reward, 矿石(meaning ore), can only cashout in "kuai coin（快币）", a virtual currency issued by QVOD, and "kuai coin" in turn can only pay for certain services as the company chooses.

Apparently, there is absolutely no consideration of privacy taken in LIULIANGKUANG, and the reward not even near to incent infrastructure building, it could't even payout the cost of net charge and electricity. So it's only a preferable option if you don't have much to do anyway while the computer is open.

So, all people concerning bitcloud, the territory you have glimpsed is still a virgin land! And if it succeeds, can really change the world for better. Best regards.
