yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
wong sau » wong sam, wong siu, wong shiu
tan hua » tuan hua, wang hua, tan chia
yan jiu » yang jie, pang jiu
man » main, many, mean

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

• Performing a fuzzy search may retrieve terms with similar spellings: man houng tan hua ban ((((yan jiu) OR (yang jin))) or (yang jun)) ((wong sau) or (kong sara)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: man houng tan hua ban ((((yan jiu) OR (yang jin))) OR (yang jun)) ((wong sau) OR (kong sara)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "man houng tan hua ban ((((yan jiu) OR (yang jin))) or (yang jun)) ((wong sau) or (kong sara)) ;*".
