There have been a LOT of Chinese Backstreet Boys (aka Back Dorm Boys) spoofs and they've all been quite bad. I know you're trying people, but I think I may have figured why they've been bad until now. You see, this seems like a rare Asian-only talent to spoof big name talent with a webcam. Just like SATs which seem to be designed expressly to be easy for Asian kids applying to UC schools, webcam spoofing remains the domain of paired-Asian males in some random location. (Note, the video starts out quite lame...just let it run and they'll get to the good stuff--it's still not great, but it's better than other spoofs I've seen).
