Do I need to bring thick clothes to Chongqing in August?

Are you talking about the Tiansheng Third Bridge in Wulong and the Rift Valley in Longshui Gorge?

Wulong Xianshan said that it is still relatively cold on the mountain, so you don't need to bring thick clothes, just bring a shawl or something.

It's still a little hot in the sun during the day, and it's colder in the morning and evening.

For example, the Warburg Hotel near the Upper Grassland in fairy mountain, where I stayed a few days ago, was covered with a thick quilt at night, and it was very cold when it was foggy.
