I watched the Chinese - all I could think when I first saw them was that they all look so young and tiny. If they were flying on a senior level 5 at worlds I'd be crying foul for sure ;)...haha.
I saw the first girl mess up on bars too - it was pretty bad, and what they showed of her warm-up looked a lot better, so it was unfortunate she messed up when it counted (I would see that at meets a lot particularly on bars - my CP doesn't like to warm up bars at all cause she says she's always the best the first time she does her routine after resting and it just gets worse as she does it more times - maybe the Chinese girl is the same way ;)).
The rest of the Chinese rocked their bar routines though - they were amazing - I think all of the others placed top 5 from what the screen said at the time, but only 2 can go to finals.
Their beam routines were good too. They had one girl on floor w/ an amazing first tumbling pass - but a lot of their floor landings as a team were just really short (not enough height to get it all in so they were landing on their knees/bent over).
They had one girl w/ an amazing vault - I think the score came up w/ her placing 5th on the event at the time, so she may have made the finals. I was actually pretty impressed w/ their vaulting considering that most of them probably weigh less than 50 pounds. When my CP was their size (back when she was 5 ;)), she could barely get the spring board to go down an inch when she jumped on it.
