Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
kyun xian » kyun pin
thanh vu » thanh van, thanh _
lei kyun » lee kyung, lee kyu, pei yun
gong hui » tong shui, wang hui, gong si
tong hui » wang hui

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) OR (yang guang)) ((ya hua) OR (thanh vu)) lei kyun xian ((gong hui) OR (tong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) OR (yang guang)) ((ya hua) OR (thanh vu)) lei kyun xian ((gong hui) OR (tong hui)) ;*.
