Is China really that serious on corruption?

Corruption begins with C and so does China.  It is undisputed that in the past, corruption has secretly been a major part of Chinese society.  Now, with new president Xi Jingping, corruption may finally be coming to an end--a slow end but an end nevertheless.  The question remains though on how hard Xi can crack down on corruption without losing his support.  If he doesn't crack down corruption quick enough, he could lose the support of his citizens but if he pushes his Communist comrades to give up their power too quickly, he will lose their support.  In essence, Xi Jingping will have a balancing act on what to do in order to do what he promised in his speech to end corruption.
