It's completely different the way they hit the ball and that's why I mostly watch only these kind of TT videos because I find them interesting and their technique and I've tried to adopt the same technique and it is very rewarding when I beat players that use fast springy rubbers and me using tacky H3 rubbers.
I rarely watch videos from european leagues, because the way they play is like as if they're trying to shoot an arrow by pulling a bow or something, whereas the chinese incorporate more martial-arts-like technique into TT and that's why imo it's more interesting to play than the european league which mostly rely on springy rubbers.
I also love watching those videos and try bringing some techniques of them in my game. What major differences did you notice to european players? For me they play much more "forward" but also somehow get crazy spin into the ball.
