Perhaps you should try some spelling variations:
kang young » wang hyoung
zhang yan » zhang fan, zhang jian, wang yan
young sau » young sae, young man, young kyu
lang yan » wang yan, wang yang, yang yang
yan guan » gan guan, yan yuan, yang guang
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
dong di » dong sin

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: ((((lang yan) OR (zhang yan))) OR (dong di)) yan guan ((yang jie) OR (yang jin)) kang young sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((lang yan) or (zhang yan))) or (dong di)) yan guan ((yang jie) OR (yang jin)) kang young sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((((lang yan) or (zhang yan))) or (dong di)) yan guan ((yang jie) OR (yang jin)) kang young sau ;*.
