U22国足29人集训名单：20人中超、6人中甲、2人中乙、1人荷乙（U22国足29人集训阵容出炉：中超20人、中甲6人、中乙2人、荷乙1人）

We need to respond carefully to the user's statement in Chinese about the U22 Chinese national football team training roster. It seems like they might be looking for more details, such as a list of names, analysis, or the team's schedule. Since they didn't specify a task, I wonder if I should ask a clarifying question to guide the conversation. I'm aware that retrieving the latest roster could require network access, but I need to be mindful of the limitations in this environment.I can paraphrase and ask what the user wants to know — whether it's a list of players, positional distribution, club breakdown, comparisons to the previous camp, notable call-ups, or upcoming fixtures. I think responding in concise Chinese and providing options for them to choose from would be ideal. I want to ensure correctness, so I should clarify that without up-to-date data, I may need their help with a link or confirmation date to proceed. Let's phrase it invitingly!
