As we know, the developers in China can not see the Youtube / Vimeo videos. So now we have added the support of Tencent Video link. If you are developers from China, give it a try. If you want your video be watched in China, give it try.
Meanwhile, We're still trying to find a solution to let the Youtube / Vimeo videos to be watched in China. It seems to be a mission impossible. If you have an idea on how to do this, leave a comment!
