The importance of air-conditioner in summer in Shanghai It's been very hot in Shanghai for almost one month. The temperature issued by the weather authority goes up to 38 or even 40 celcius degrees. Not mention the real temperature on the street. During the day, even at a very early morning, you have to go out with your anti-sunshine umbrella. It used to be only women who brought umbrellas with them. Nowadays, it is so common to see a man who uses an umbrella to guard himself from the sunshine. At dawn, the heat is less intense but still the air feels very warm. Sometimes a breeze is here but the breeze is also very warm. During the night, what do you do if you don't have an air-conditioner? The answer is to stay awake untill the sleepniess takes you into sleep and then the heat awakens you and then again the sleepniess takes you into sleep. You repeat this cycle. Eventually, you spend money to install an air-conditioner to get a good sleep. Air-conditioner is the only tool that can help you get through this crazy summer.
