Hard-liners in the party and especially the military stated that "art and literature must serve politics", while moderates were willing to tolerate apolitical material. Nonetheless, writers and artists were still told that their primary job was to "educate the people to believe in socialism". As such, the party took a stand against certain Western ideas and philosophies, as well as abstract theories of human nature. Highly personal poetry and discussions of the subconscious were viewed as representing an "unhealthy" tendency. Officials also took a stand against pornography, which was being imported from Hong Kong in large quantities. This was coming at a time when many young people were skeptical of the party's leadership and increasingly questioning whether it was really possible to achieve socialism or if doing so was desirable. Nonetheless, the authorities tolerated Zhao Cuan's play "Marx In London" which was compatible with official viewpoints in that it presented the communist founding father as a mortal man who lived in a different age and whose theories could not provide the answers for all of China's present-day problems. On the other hand, the writer Liu Binyan, who had been in and out of favor since 1957, was criticized for his novel "A Different Kind Of Loyalty" which suggested that the Communist Party was not infallible, nor should it be followed without question.
