In a dormitory of a university in Wuhan, some students filled mineral water bottles and made a DIY water bed to cool down; in another university, boys bought a mini inflatable swimming pool online and sat in it to play cards and eat instant noodles; in a dormitory of Hunan University of Technology, boys lived together on the roof; Some students from Nanjing Institute of Technology came to the library to escape the summer heat; students from Guangdong University of Technology and Guangdong Foreign Studies University hugged winter melons to sleep. "It was quite cool and I slept until dawn"... The creativity of the masses is unlimited, even if there is only one melon. . .
