The US has the opposite extreme of this problem, where we get 6 months for the same white collar crime but there's a minimum 5 year sentence if you grow a specific plant to treat your dehibilating asthma symptoms (http://www.hr95.org/pinson.htm).

I was going to make a quip about how you would probably fare worse in China, but at least according to Wikipedia, the penalty is 10-15 days [0]. On the other hand, legalization is probably imminent in the US. The same is not true of China.

Extreme (death penalty) sentencing for corruption is generally not something you see in regimes that have highly effective regimes of anti-corruption enforcement.

It is however, a highly effective tool for political purges.
