Subject: Winter
Dear Flora,
Thank you very much for your lovely letter. I am glad to hear from you. In winter here, the weather is usually cold, and it often snows. I like winter because I enjoy skiing and skating, which are popular winter sports here. As for the New Year, we celebrated it with a big family dinner and fireworks. We sang songs, and everyone was happy. I also wish you could visit us someday in winter to see our snowy landscapes. Thanks again for your letter. I look forward to your reply.
Best wishes,
[Your Name]
