Hi TTFC, a Chinaman is a leg break delivered by a left handed bowler. So, you can use the information available for leg break bowling.
Terry Jenner has done a couple of useful videos on the BBC site where he demonstrates the different grips and actions. Click on Shane Warne's picture to open the BBC video player.

Since Chinaman deliveries are left-handed versions of the leg-break why not contact the ECB for info on bowling clinics for leg-break bowling?
