What equipment should I bring to Jiuzhaigou in mid-July? Especially in dress, what thickness coat, thin sweater or jacket should I bring? I hope it can be more detailed.

I just got back from Jiuzhaigou. Now it begins to rain in Jiuzhaigou. First of all, be sure to prepare a thicker coat. It's cold there in the morning and evening. Personally, I don't think altitude sickness is too serious, so I don't need to bring any medicine. If you are weak, buy medicine to prevent altitude sickness in advance before departure, and never buy it in the scenic spot. More than 100, and more than and there are more, very cheat people! It will rain a little more in Jiuzhaigou in July.

Jiuzhaigou is about 3000 meters above sea level. The plateau climate is humid and the top of the mountain is covered with snow all year round. In spring, the temperature is low and changes greatly. The average temperature is mostly between 9℃ and 18℃, with frozen soil and residual snow before April. In summer, the temperature rises rapidly and steadily, with an average temperature of 19℃ to 22℃. It is cold at night, so it is advisable to prepare a thin sweater. In autumn, the sky is crisp and the climate is pleasant. The temperature is mostly between 7℃ and 18℃, and the temperature difference between day and night is large, especially in the late autumn after 10. You can wear two clothes or even single clothes during the day, and you have to wear sweaters or even winter clothes at night. Frozen soil appeared in late June of 10. It is very cold in winter, and the temperature is mostly below 0℃. The rainfall in Jiuzhaigou is small and concentrated (the annual rainfall is less than 600 mm), and July and August are typical rainy seasons. It is suitable to travel to Jiuzhaigou in late spring and early autumn, preferably from late September to 10.
