Actually I dunno, after yesterday evening China's men had athletes bomb in 4 weight classes, which is unheard of!
I think the deal is inexperience on one count (US lifters) and z0mg-uber-overhype-kthxdieMaStrengthFacebookvidz (Chinese lot).
Nobody expected much from the US lifters, and they delivered on those expectations; on the flip side, everybody thought Liu Xiaojun nad Tian Tiao were going to clean up... and they didn't.
It's one thing being the best on Youtube; another being the best on the platform on the day.
