Nowadays, teen girls have much more problems than teen boys. There is no exception in the Chinese badminton youth team (or 2nd team). Teen girls were used to be easier to manage before, that was the reason, China's female players achieved more than male players. Now things are different, in the Chinese badminton 2nd team, boys are good, concentrating on training, while girls are causing all kinds of troubles. The managers and coaches failed to manage the girls in the national team now, especially in the 2nd team. That's the reason, now Chinese boys outperformed girls at the Aussie open. The total win-loss for CHN 2nd team WS is : 8-4. The total win-loss for CHN 2nd team MS is : 19-3.
