Jetjockey145, there are many threads here about the Chinese medical here so read up.
I do not want to scare you but there's a 50% plus failure rate for the ASTRONAUT medical that the CAAC administers. From microscopic kidney stones, color blind, heart rate, scars, medication, etc, these "doctors" will look for everything and more. First class FAA (ICAO) standards medical multiplied by ten!
Even pilots that have passed previous medicals on multiple occasions are now failing. All I can say is make sure that you are in somewhat good shape and PRAY!!! Today you fail, tomorrow you'll pass, as there's no consistency used by these so called "doctors"... Preventing qualified candidates to fly in China! Sad...
My .02 cents
