On May 19， the Supervision Department of Central Discipline Inspection Commission announced on its website that Cao Lixin， the Central Discipline Inspection Commissions deputy bureau-level Inspector and Supervision Commissioner， was under internal investigation for suspected serious law and discipline violation.

Cao Lixin is the second interior official of the Supervision Department of Central Discipline Inspection Commission who got investigated in ten days. The first was Wei Jian， director of the fourth Discipline Inspection and Supervision Office.

Same as Wei Jian， Cao Lixin also once worked in the Discipline Inspection and Supervision Office. From 2007-2011， he served as one of the section chiefs in the Sixth Discipline Inspection and Supervision Office which was in charge of the government graft investigation in North and Northeast China.

After the second round of institutional restructuring， the Central Discipline Inspection Commission founded the Official Oversight Office to fight against law and discipline violation inside the organiazation. According to preliminary number， there had been three “insiders” of the Central Discipline Inspection Commission that were investigated since then， including Cao Lixin and Wei Jian. The other one was Shen Weichen， a member of the commission.

“The fact that several officials inside the Central Discipline Inspection Commission are investigated sends a positive message to the public. It shows that the Commission is not afraid of self-inspection and self criticism and will act as a deterrent to others.” said Professor Xu Yaotong with Chinese Academy of Governance.
