Students sleep on the floor of an air-conditioned gymnasium to avoid the heat in their dormitories at Central China Normal University in Wuhan city, Hubei province, on June 21, 2013. The university opened its gym to students as the heat wave lingered in the city. Besides the gym, all the university's air-conditioned venues, meeting rooms and halls are open to students, who are also provided with mats. The recent scorching weather in South China has triggered widespread complaints about the living conditions of university students, whose dormitories are not equipped with air conditioners. Some of them called for the university to install air conditioner in the dorms. [Photo/CFP] ]
