The last year is worth learning from, and this year has come to an end

On the 23rd, people went up to the mountain to see the snow at the source of the Huangpu River, Longwang Mountain (Changtan Village). I was prepared for the low temperature at the top of the mountain, but the actual feeling was much colder than expected. This time I brought a lightweight hiking tent. In the environment of minus seventeen degrees, I didn't feel cold in the tent. The main thermal sleep system is - hot water bottle - R value 6.9 inflatable mattress - minus 20 degrees temperature standard down sleeping bag - two warm babies The fact proves that I slept very well. When I woke up and opened the tent, I was shocked by the fog and snow scenery. Everything was worth it.
