Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang ying » wang yang, wang yong, wang jing
sang minh » kang minah, anh minh, song min
yang jin » yang jie, yang jun, ying jin
tang min » chang min, yang mind, tang li
hong sau » wong sau, hong paul, kong sar
yang li » yang lin, yang di, yang xi

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ying ((((yang li) or (yang liang))) or (yang jin)) ju ((tang min) OR (sang minh)) hong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ying ((((yang li) OR (yang liang))) OR (yang jin)) ju ((tang min) OR (sang minh)) hong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((((yang li) or (yang liang))) or (yang jin)) ju ((tang min) OR (sang minh)) hong sau ;*".
