Clarifying the date inquiry

The date "12月19日" indicates it's a post date. I think the best approach is to ask the user for the source link or request permission to search the web. Since this question likely requires external info, I should ask if they want me to summarize a specific article from December 19. I could suggest searching for Chinese sports news as an option and make the request friendly!Formulating the response

I need to craft my response in Chinese and offer two options: first, the user can share a link or text, and second, they can let me search the web for sources. I'll mention that I can summarize in 3-5 bullet points to keep it concise. It’ll also be helpful to ask the user how in-depth they want the summary to be. This way, I can better tailor the response to their needs!
