wong sau » wong sam, wong siu, wong shiu
yan yan » yan yuan, nan yan, wang yan
hua ren » hua chen
jing ji » ying jin
wang » wing, wan, lang
sar » sara, star, saur

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan yan) or (yang yang)) hua ren ((ying jie) OR (jing ji)) ((wong sau) or (kong sar)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yan) OR (yang yang)) hua ren ((ying jie) OR (jing ji)) ((wong sau) OR (kong sar)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) or (yang yang)) hua ren ((ying jie) OR (jing ji)) ((wong sau) or (kong sar)) ;*".
