Travel back to the US first, and enter with your Chinese passport. Get an entry stamp. Then fly to China, using your Chinese passport. You should be ok, since the last stamp is the US. Where you're coming apparently from.
However, if the Chinese immigration dud(in)e is awake at the wheel, you might face a few questions, regarding where you were in between.
Flying to China is never 100% safe for dual citizens.
