What's the weather like in Lugu Lake in February these days, and what kind of clothes are suitable for spreading?

During this time, the weather in Yunnan is particularly dry, and so is Lugu Lake, but the temperature difference between morning and evening is large, or it will feel cold even at noon as long as it is not in the sun. I went in early February, and there is water on the road, which will freeze in the morning. So it is best to have a down jacket that is not too bloated.
