Providing report options
I'm summing up that the U22 China team will reconvene on December 7 for a month-long camp. We want to avoid fabricating details, so I should mention that the goals might be to prepare for the Asian Cup U23 or Olympic qualifiers. As of 2025, the U22 is for the 2003-2004 age groups, potentially preparing for the 2026 U23 Asian Cup. If the user wants, I can check the latest roster and schedule. I’ll ask for their preference on details!
