Yang Jinrong was once a rising star of Ran Ran in the police force. He is very cautious, clear-headed and highly vigilant. Coupled with his loyalty, the police sent him to work undercover with Chen Han. In order to gain Chen Han's trust, Yang Jinrong obeyed Chen Han's orders and went to the police station to be "undercover" to help Chen Han know the inside information of the police.
Yang Jinrong later found out Liu Jianming, the biggest mole in the police station, but at this time Liu Jianming was bent on turning over a new leaf. Liu Jianming wanted to eradicate everyone who knew his true identity, so he killed Yang Jinrong, and Yang Jinrong finally died under Liu Jianming's gun.
