If you just google 'chinese name applied to buddhist saint achieved spiritual perfection' you'll find the name in the banner of one of the first few websites featured. Hope you understand what I mean. Good luck.
Thanks marje, but still no joy. Have spent so much time on this now, only word I could find was arhat but cannot find an actress of that name. Have checked Thesaurus and Advanced Google - no luck. Never mind, thanks again.
