Perhaps you should try some spelling variations:
wang kyoung » wang hyoung, hwang byoung, wang yong
wong shiu » wong siu, cong shu, song shin
yang hua » wang hua, yang hui, ying hua
wang hui » wang hua, wang zhi, wang wei
dan yang » daun yang, tan yang, wang yang
yang jun » yang jui, pang jun, yang jin
lai » laid

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: "wang kyoung ((yang hua) OR (wang hui)) dan yang jun ((wong shiu) OR (wong lai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang kyoung ((yang hua) OR (wang hui)) dan yang jun ((wong shiu) OR (wong lai)) ;*.
