The sweeping anti-graft campaign has created a good atmosphere for Chinese writers and artists to write stories about the topic, but classic works are still very rare, a seasoned screenwriter said at the ongoing two sessions Tuesday.

"The anti-graft campaign has exerted a great impact on Chinese society, but we see few art works reflecting it, and the ones we do see are superficial," Wang Xingdong, vice-chairman of the China Film Association, told the Global Times on Tuesday.

The primary audience for films is young people, while the target audience for anti-graft topics is older. However, a deeper problem is that private investors are concerned about investing in films on these topics, said Wang.

Wang had to send dozens of letters to some central government leaders to seek screening opportunities for A Murder Beside Yanhe River, a film he wrote including anti-graft elements, before it was eventually screened in December 2014.

"Films and television programs about anti-graft are important in promoting the rule of law and ideal for praising virtue and denouncing vice," Wang said.

He added that the cause has now earned support from the country's top disciplinary watchdog.

The current anti-graft campaign has made its mark on art and literature circles, with many members of the 12th CPPCC National Committee saying the best way for writers and artists to participate in the campaign would be to create sharper, more critical works, news portal people.com.cn reported.
