What's the weather like in Beijing in July? How to dress when traveling? What should I do if I encounter a sandstorm?

Comrade, there is no sandstorm in July. If you want to meet someone, just bring summer clothes. It won't be above 30 degrees every day. At least I was born and raised in Beijing for 24 years. I have never met Beijing in July, but taking an umbrella can protect me from sun and rain.
