1. If you want to feel the warm winter sun, go to Yunnan, Lijiang, Dali, Lugu Lake, etc. The weather is excellent.
2. Go to the northeast if you want to feel the scenery of the season. Snow and ice sculpture skiing will definitely give you a different feeling.
3. West Sichuan line is also worth a one, Jiuzhaigou, Hailugou, Darku Glacier, etc.
