hey dude! I watched Tuan Anh's video long time ago. If you read that journal again, you can see that they talk about FW 2.2 . Mr. Tuan Anh's work also appeared on our television at that time. I am not sure they can do it now. However, in Vietnam, I reckon someone could do it, of course, with a high fee that I really don't want.
