BEIJING - Despite the investigation and prosecution of hundreds of officials across the country, the countercorruption drive is showing no signs of letting up.

In the two years of the campaign, the anti-graft watchdog has ousted corrupt officials all the way from low-level "flies" to high-ranking "tigers."

Yu Yuanhui, a member of the Communist Party of China's (CPC) Standing Committee of the Guangxi Zhuang Autonomous Regional Committee, is the latest official placed under the spotlight.

It was announced on Friday that Yu, who is also Party secretary of Nanning, capital of Guangxi, was under investigation for alleged "severe disciplinary and law violations".

Not content with just caging tigers and catching flies, the authorities aim to implement a permanent and effective anti-corruption system.

Leadership reshuffles at provincial-level discipline inspection agencies are one of the most recent efforts to rein in graft.

Wang Yanfei, former secretary of the Commission for Political and Legal Affairs of Ningxia Province, was appointed as head of the Sichuan provincial discipline inspection commission on Wednesday.

Six provinces had new heads of discipline inspection agencies installed in the first five months of 2015, while between 2012 to the end of 2014 only eight provinces saw leadership changes.
