Perhaps you should try some spelling variations:
nana yaan » nan yan
shang hai » shang kai, dang hai, chang ha
nana yaa » nan ya, nan yan, nanay a
ren kang » jin kang, ren weng, ren yan
kang min » kan min, tang min, kang minah
hong hai » zhong tai, dang hai, hong tan
hua ren » hua chen
wang » wing, wan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((nana yaan) OR (nana yaa)) hua ren kang min ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((nana yaan) or (nana yaa)) hua ren kang min ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) ((nana yaan) or (nana yaa)) hua ren kang min ((hong hai) OR (shang hai)) ;*.
