The decade is one of the twelve short stories from the Ha Jin's Under The Red Flag collection during the Chinese Cultural Revolution. In the story we can recognize a few topics, such as "forbidden sexuality" when the pretty teacher Zhu Wenli was caught in a compromising situation, because all kinds of "deviations" in Mao's opinion were forbidden. Also, the influence of bourgeois practices is forbidden and strictly punitive, meaning another topic would be, prohibited "harmful influence". As well as an even more obvious topic that has to do with the previous ones, these are "forbidden books", when teacher Zhu Wenli was in trouble due to the interpretation of Chairman Mao's writings. Nevertheless, a topic that is primary and which appears as a reaction to all the above mentioned topics, as well as resolution, that the influence of old ways of thinking should be cleaned, is China's youth rose up tu purge four "Olds", old culture, old habits, old customs, old ideas. This would create conditions and a path to the future.
