young ghi » hong ghi, young get, young hr
yang jui » yang judy, yang di, yang xi
jui gene » i gene, iii gene, jui meng

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: wang yang yang jui gene ((yang kim) OR (yong kim)) ((young ghi) OR (young choi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang jui gene ((yang kim) OR (yong kim)) ((young ghi) or (young choi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang jui gene ((yang kim) OR (yong kim)) ((young ghi) or (young choi)) ;*.
