Zhang Jingsheng was known as the first sexologist in China, but at that time, all Zhang Jingsheng's views were shocking. As the saying goes, half a step ahead of the times can succeed, but more than half an era ahead may be a disaster. This also makes life difficult for Zhang Jingsheng.

The History of Sex was edited by Zhang Jingsheng at that time, such as Xiao Jiangping's The First Sexual intercourse, which was preceded by Zhang Jingsheng's preface. Every article has comments added by Zhang Jingsheng. His straightforward brushwork angered the headmaster of Nankai School. Zhang Boling, the headmaster, wrote to the police department and said, "obscene books are the most important, and teenagers are harmful to read them." Then, just four months later, The History of Sex was banned, and Zhang Jingsheng had to leave Peking University because of the situation.

At that time, Zhou Zuoren also "supported" Zhang Jingsheng in Yu Si. Although the words were neither favorable nor derogatory, they were considered as "support" at that time. Zhou Zuoren said that he had read the book "The History of Sex", and he didn't feel anything, let alone be a scourge, but he would still stop his children from reading this book. Obviously, at that time, Zhou Zuoren's thought was very open and cutting-edge compared with ordinary people, but it was still not as good as Zhang Jingsheng's.
