China's bench can easily win this qualifying tournament so Zhu is only there as insurance. The random team during Asian Championships managed to get 4th place so the group China is in is relatively weak. If An can't win with the bench, it only means he's too incompetent.
As for U23, it's pretty much a meaningless tournament since it was newly added a few years back so winning it is not important like U18 and U20. Think of it as a consolation tournament for players to win something.

Yeah FULLY Agree the only purpose that does give some sense to the U23 existence... cannot be mean trying to bag all!
