阵容不整，U22国家队今日训练仅18人参加（U22国家队阵容不齐，今日训练仅18人到场）

Creating options in Chinese

I need to provide options for the user in Chinese: 1. Summarize key points, 2. Analyze reasons and impacts, 3. List absentee names (sources needed), 4. Write a brief or tweet, 5. Track follow-up reports (with links).

I'll avoid asking to open any network and keep my response concise. It would be good to ask for more details, like which U22 team? Training camp location and time? I should encourage them to provide any source links or screenshots if possible.
