BEIJING, Jan. 22  -- A recent survey found 70 percent of respondents were satisfied over the progress of the country's anti-graft campaign, China Youth Daily reported.

The respondents listed the downfall of a batch of "big tigers" or high-ranking officials, cracking down on corrupt officials fleeing abroad, and a purge of "naked officials", which refer to those whose spouse and children have emigrated overseas, as the top three biggest results in 2014.

The survey sampled 2,167 people, with employers ranging from private and state-owned companies to government agencies.

Some 82.3 percent of those polled, however, believe the situation remains grave and the fight against graft still has challenges ahead.

The most anticipated anti-graft moves in 2015 include bringing down corruption in common people's daily life, ferreting out more "big tigers," and the continued hunt for fugitive officials and their illegal gains, the survey said.

After taking the helm of the Communist Party of China in November 2012, top leaders resolved to target both high-ranking "tigers" and low-ranking "flies" in their corruption fight.

Among the highest-ranking officials downed last year were former state leader Zhou Yongkang, former military leader Xu Caihou, and former senior political advisors Ling Jihua and Su Rong.
