Wang Ling, a 27 year-old IT engineer from Chongqing municipality, recently received a special short text message signed from the Beibei district procuratorate.

The message said: "To crack down on corruption is our common goal. Beibei District Procuratorate will offer a reward to informants for reporting corruption from 3,000 ($440) to 500,000 yuan. The hotline is 68342000."

"Some of my colleagues and relatives also received this text message. It is really a fresh way to reach citizens instead of posting a notice on the website," Wang said.
