If you can accept high temperature, I think it will be Ok. In July, the weather is very hot. Although hotels, shopping malls, supermarkets and many places are equipped with air conditioners, it's still very hot when you walk on the street. Kunming in Yunnan is nicknamed 'Spring City'. The temperature there is always very good all the year round. Another place is Tibet. Due to high altitude, the temperature there is not high. It's the coolest place in China.
