Wang Jun was an owner of a teahouse in Chengdu. In his teahouse, he had placed fishing machines (video game machines) to attract and entertain clients. On June 4, a Mr. Mao and three other people came to the tea house and told Wang that someone surnamed Zhang was cheating money out of the machine. Wang and Mao went to check and found that Zhang was playing the fishing game. They held Zhang under control and questioned him, but Zhang denied that he was cheating. He was beaten by Mao and his fellows and had his two ribs broken, which was later confirmed as “minor injury”. However, Wang and Mao searched out tools for cheating on Zhang. Wang started a negotiation with Zhang and Zhang paid RMB3000 to Wang as compensation. Mao and his fellows also forced Zhang to give them RMB5000 before letting him leave. The local prosecutor ordered an arrest against Wang on account of robbery and opening a gambling house. 

Among the four defendants in this case, Wang was listed as the second-mentioned defendant. Wang’s family entrusted attorneys Leng Yunsong and Liu Wan to represent Wang. The attorneys, after a careful analysis, believed Wang’s behavior did not constitute a criminal defense. They communicated this point to the police and the prosecutor and suggested the police revoke coercive measures and the prosecutor dismiss its arrest order against Wang. However, their opinion was rejected by both the police and the prosecutor. Wang was arrested and accused of robbery. While the prosecutor was looking into the case, Leng Yunsong and Liu Wan again communicated with the prosecutor to the effect that the prosecutor charged Wang of intentional injury instead of robbery and opening a gambling house. The attorneys once again thought this accusation not appropriate. In the end, the prosecutor decided to charge Wang of robbery and opening a gambling house and brought the case to court. 

To argue for Wang, Leng Yunsong and Liu Wan prepared a number of defense strategies beforehand. During the trial, they did what they could by applying various defense skills and used expertly relevant law theories. 

During the eight months in which seven court sessions were opened, the attorneys argued persistently that Wang’s behavior did not constitute criminal defense. Their arguments were eventually adopted by the court, with Wang becoming the only one not found guilty among the four defendants. The prosecutor gave up protestation against the decision. It was learned that the Intermediate People’s Court of Chengdu would have a press release over the case recently.
