You asked "How many civil servants in all levels of governments are there in China?"
the term "civil servants" alone does not include political organizations, as in the us. but in china, civil servants is just a portion of the government body, the other portion is ccp cadres, you didn't count in.
ccp cadres are the staff that are tasked with the management of party affairs in full time, though it could be involved in government tasks but in much smaller scale. the number of ccp cadres is a secret of the ccp, it has never been revealed to the public, although ccp with 99 million members is the second largest party in the world, next to bharatiya janata party in india.
if you want to make it convincing, comparing apple to apple not apple to orange, you need to include ccp cadres in the equation.
