I found out there's a multitude of amazing rare high quality videos on Youku!
Here is a link to a full Massive Black video with Jason Chan: http://v.youku.com/v_show/id_XNDEyOTA4N ... -1.1-1-1-6
Some of these videos are literally impossible to find even if you're willing to spend money.
To the right of the video there's even more tutorials and rare videos such as, Ruan Jia, Hoooook, and other amazing Eastern artists doing paint-overs or streaming.
The downside is that it's all in Mandarin lol, and you may need to disable adblock and/or make an account to get the video to work.
