What clothes should I wear to Zhangjiajie on National Day?

At present, the temperature difference between day and night in Zhangjiajie is quite large. It's cold at night and warm during the day, but you can still wear long sleeves. Maybe the temperature will rise in 1 1 month, but you can still bring all kinds of clothes appropriately. And if you go to Zhangjiajie Forest Park, the mountain is cold, you can take a coat appropriately, but you will be fine if you exercise more on the mountain.
