What's the weather like in Jiuzhaigou, Chengdu on August 26th, 27th and 28th?

There is a great temperature difference between morning and evening. It was still raining lightly in Jiuzhai a few days ago, but it cleared up these days. If it rains, wear a thin down jacket; If the weather is fine, you can even wear short sleeves by noon. In Jiuzhai, you can feel it all year round. Better bring more winter clothes. In fact, short sleeves are basically not used, and ultraviolet rays are very strong.
