Clarifying user intent

I’m considering that "3-CH" might reference "三朝." The user could want to polish, rewrite, or translate this into English. Common tasks would be translations or refinements. I think it’s essential to ask for clarification here, something like: "你想让我做什么？翻译、润色、改写成标题、还是扩写成一段新闻/微博？"

My goal is to provide a natural English translation, a polished Chinese version, and a headline variant, while keeping it concise and formatting light.
