Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
kang dong » kang young, jeng dong
yan tang » tang tang, yan liang, yan zhang
yan wang » yuan wang, qian wang, yan liang
jin kang » jin chang, jin kyung, jing fang
wan yan » wang yan, nan yan, wai yan
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yan) or (dong di)) nan ((((yan tang) OR (yan wang))) or (yang yang)) jin kang dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (dong di)) nan ((((yan tang) OR (yan wang))) OR (yang yang)) jin kang dong sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (dong di)) nan ((((yan tang) OR (yan wang))) or (yang yang)) jin kang dong sin ;*".
