Though Wang Xiaofang refuses to place his works in the category of so-called officialdom literature, he is still considered an important force of this much-loved genre.

On average, officialdom novels sell at least 100,000 copies, according to Qingdao-based Peninsula City News. They frequently top bestseller lists for both bookstores and online reading, soaring to millions in sales.

Experts say readers look to the books to peep into scenes they're eager to know more about and to learn workplace skills.

"Unlike other writers' books, reading my books can't lead you to the ways of promotion in your career life," Wang says.

Fudan University professor Zhang Taofu believes the craze also shows Chinese people's ongoing fascination with political power.

"The lack of full transparency in power operations in a sense raises public curiosity in digging out the dirt behind the scenes. That's why officialdom novels are popular," says Dun Li, as quoted by Chinawriter.com.cn.

Though some critics argue Chinese writing on the theme goes back hundreds of years, Wang Yuewen is recognized for starting the contemporary trend in 1999 with his novel Ink Painting. His latest work Greenish Yellow echoes his sharp satire and observation on corruption and power fights among county-level officials.
