What's the weather like in Zhangjiajie around July 20th?

I'm here now, and the weather is fine. It rains a little occasionally, which is quite cool. Usually it's hot, about 25~34, with long sleeves and a little cold at night.

If you really want to play, I suggest you wear flat shoes or sneakers, and never wear high heels!

Also, be prepared to climb the mountain for a long time. Don't expect too much here. If you don't appreciate it, the essence of coming to Zhangjiajie is to climb mountains and see a bunch of grotesque rocks, at least for me.

Also, if you are a student, you can save nearly half of the tickets by bringing your student ID card.
