Stay cool in ancient ChinaWith the coming of hot summer，it's difficult to imagine our lives without air conditioners.So，without them，how did the ancient Chinese cool themselves in the summer heat？
    Although the ancient Chinese were more conservative（保守的），the summer heat could drive anyone mad.To keep cool，women would wear thin silk clothes.These clothes were not just for women；men wore them as well.For people living in the middle and lower reaches（下游） of the Yellow River，clothing made of bamboo was popular.
    Without fridges，natural ice was the key to making cold drinks in ancient China .In summer，in addition to cold wine，people also enjoyed icy lich juice and shaved ice.
    It's said that Kublai Khan，the founder of the Yuan Dynasty in China，loved to drink milk and would add ice to the milk to make it last longer in the summer.He also added jam to his favorite icy drink，creating the world's first ice-cream prototype（原型）.
    So where did they keep ice to prevent it from melting in the summer heat？During the Warring States Period，ice was kept in a device called bingjian（冰鑒） to make cool drinks，which was made of metal.
    For the emperors in ancient China，especially during the Qing Dynasty，the Mountain Resort（避暑山莊） and its Outlying Temples in Chengde，Hebei Province，were places where they spent their hot summer days.
    Besides，the royal family could also stay cool in the Forbidden City.There were five ice cellars （冰客） for ice cellars for storing ice throughout the year.In winter，thick ice would be cut from rivers and placed inside the ice cellars.No light or heat from the outside could enter the cellars.As many as 5，000 blocks of ice could be put in each one，and the doors wouldn't be opened until the next hot summer.
