In the last mission, there was one manual docking and at least 2 or more automatic dockings under different conditions, one of them to test docking sensors in the glare of the sun. I think the unmanned Shenzhou 8 also did perform 2 or more automatic dockings.
Docking with the ISS is different in that it is always done with the help of a robotic arm which pull in the spacecraft for the last few metres. I suppose the Chinese space station may also adopt this method once it's installed with a robotic arm possibly to simplify docking maneouvre.
