Thirst for Knowledge

Colorful thermos flasks lined up in rows-a sight from the campus of Nanjing University. Students living in the dorms take their flasks with them when they head to class in the morning and place them outside the hot water room. By the time class lets out, the flasks will have been filled by campus workers. The students head back to their dorms with books in one hand and a thermos flask in the other, ready for a meal and an evening of study.
