Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yan » yang yang, wang yan, yang fan
yu cheng » yu chen, _ cheng
wong sam » wong sau, kong sar, von sam
yang xi » yang jui
yang yi » yang jui
yan yu » yun yu, yan yuan, yang yue
lai » laid

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang yan yu cheng ((yang di) or (((yang xi) or (yang yi)))) ((wong sam) OR (wong lai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yan yu cheng ((yang di) OR (((yang xi) OR (yang yi)))) ((wong sam) OR (wong lai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yan yu cheng ((yang di) or (((yang xi) or (yang yi)))) ((wong sam) OR (wong lai)) ;*".
