Responding in Chinese about football training

I need to respond to the user's statement in Chinese, which mentions that the Chinese national football team's training camp has entered a closed phase, leading to limited external information. The user might be looking for commentary or updates, so I should clarify what they want to know—like lineup or rumors. I’ll provide a brief analysis, mention typical reasons for a closed camp, and suggest reliable sources for updates. Additionally, I could offer to summarize any official releases later.Explaining closed-camp communications

I can explain how closed-camp communications typically function. I'll consider structuring my response with bullet points. I could also ask the user what specific aspects they're interested in, such as roster, injuries, warm-up matches, tactics, or opponent intelligence. Additionally, I can suggest reliable channels for updates, like Weibo or major sports news outlets. I should offer some tips on verifying information too. The focus will remain on sports, so no need for political discussions. I'll keep everything concise!
