What is the common view of the Japanese regarding China?

China is a rapidly growing country economically and in scale. Populations are too huge, and so most Japanese think the Mao-Communism must have been such a boring society so sex must have been the only recreational activity for most Chinese. In politics, most of the Japanese think the government is taking advantage of the history of Japan invasion to control out burst of people's anger. In daily life, growing rate of Chinese crimes in Japan is getting a big issue.
