I probably went looking for them once, and didn't have any luck. There may be store in taiwan or hong kong though, that have chinese versions. I have spent some time over the last 15 years trying to collect english translations of the book Master Nan mentions in Working Towards Enlightenment, as well as, his other books. I have a acquired some, but many do not exist in english yet and some i will guess will take a very long time to translate.
On a Zen note, Master Nan's Diamond Sutra Explained is well done http://www.amazon.com/Diamond-Sutra-Exp ... 0971656126
So is The Story of Chinese Zen. i'm on dial up so, sorry i didn't supply the link for it as well.
