diàoyú zhífǎ 钓鱼执法
The inducing of a person to commit an offense they otherwise would not have by law enforcement; literally "enforce the law by fishing."
Perhaps the best known example of entrapment in China is the case of Sun Zhongjie in 2009. A new driver for a Shanghai construction company, Sun was stopped by a man on the side of the road, shivering in the cold. The man asked for a ride, and Sun complied. Though Sun did not request it, the man handed Sun money when he reached his destination. Next, the man revealed his identity as an undercover police officer and detained Sun for driving an unlicensed taxi. Sun's conviction was overturned after netizens let loose a torrent of discontent.
The Sun Zhongjie case is parodied in the video "War of Internet Addiction."
A nearly identical case, dubbed "Fishing Gate", occurred a month earlier in Shanghai.
Wugou (@吴钩): Survey: 1. Soliciting a prostitute as a result of entrapment; 2. having your private dinner conversation uploaded to the Internet and turned into fodder for gossip. Question: Which of these are you more afraid of, given that you can only select one of the two options? (April 9, 2015)
