What clothes should I wear to travel to Shanghai at the end of July?

Due to abnormal climate and urban heat island effect, the weather in Shanghai is very hot in summer. At the same temperature, you can't feel such obvious heat in the countryside, because the countryside is covered with vegetation and there is not much automobile exhaust. The city is a cement floor, which receives much stronger thermal radiation. Because of the high-rise buildings, it is difficult to dissipate heat, so the heat island effect is formed. Usually, the actual temperature is higher than the predicted temperature. If you come to Shanghai, there is no problem indoors, but you need to prepare anti-ultraviolet equipment when you go out. It is recommended to wear light-colored, light and sweat-absorbent clothes, and also pay attention to avoiding peak crowds. I don't know if you have been there. It's terrible. It is usually from 7: 00 am to 9: 00 am and from 5: 00 pm to 7: 00 pm. It is recommended not to take the bus or subway. If you want to see how many people are at the peak of Shanghai, that's another matter. Ha ha! Are you ready? Good luck!
