Section chief is the lowest position of authority in the Chinese official system; the lance-corporals of Chinese communism. Which adds mystery to the current corruption scandal wowing China:
Even with seemingly intense competition, though, one lowly official appears to be in a class of his own. If state news reports are to be believed, investigators found 120 million renminbi, or $19.6 million, in cash in his home. As well as 37 kilograms, or 81.6 pounds, of gold. And ownership documents for 68 homes.
Thus did Ma Chaoqun furnish his modest abode in Hebei province, apparently with the illicit takings available to a very junior manager in the Urban Management bureau of the city of Qinhuangdao. There is much speculation about how he managed to make that sort of money, with some of it focusing on Ma's role in supplying water to the top leaders resort compound at Beidaihe.
It seems to me that the obvious answer here is that Ma is in fact a professional criminal who operated under cover of a no-show job with the local authority, in the manner of Henry Hill of Wiseguy fame. So the official corruption nexis here maybe concerns how he managed to wangle that.
