But that only marked the beginning of the battle between Han and Fang Zhouzi, who is known for his campaigns against pseudoscience and various frauds in China.

On January 19, Fang opened fire by publishing several articles analyzing Han's writing and accusing him of hiring ghostwriters.

Fang said that in some articles on his blogs Han had used various styles with some appearing to be in a more mature style such as that of his father Han Renjun. He backed up his doubts by saying Han had failed Chinese many times at school.

Han's publisher said Han had collected more than 1,000 pages of his novels' original manuscripts and would hand them to authorities for identification to prove that he worked on the novels on his own.

"Fang has distorted the truth and misguided the public to reach a false conclusion and spread it wildly to damage Han's reputation," Lu said.

In his blog, Han wrote: "A writer's hardships in the past dozen years might just be ruined by a rumor and the performances of several men."

Lu said Han and his lawyer were preparing for the lawsuit and a decision on whether the court would accept the case would be announced soon.

Fang wrote on his blog: "It's Han's right to sue me and it can attract more people to pay attention to the incident and learn the truth behind it. It's not a bad thing. I analyzed and doubted Han and his articles are not violations to his reputation, while Han damaged mine by insulting me and my family online."

Han, 29, was 48th in "The World's 50 Most Influential Figures 2010" in UK magazine New Statesman.
