Perhaps you should try some spelling variations:
liang sudan » liang dan, liang sun
yang liang » wang liang, yan liang, yang yang
sudan chen » sudan ch
wing yang » wang yang, ying yang, wang yan
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, kong sar, von sam
yang yi » yang xi, yang jui
lai » laid

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: wing yang liang sudan chen ((((yang yi) OR (yang di))) OR (yang jin)) ((wong sam) OR (wong lai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yang liang sudan chen ((((yang yi) or (yang di))) or (yang jin)) ((wong sam) OR (wong lai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing yang liang sudan chen ((((yang yi) or (yang di))) or (yang jin)) ((wong sam) OR (wong lai)) ;*.
