yan guan » gan guan, yan yuan, yang guang
guan hua » tuan hua, gui hua, tan hua
hua rain » hua ban, hua ren
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong lai
wang » wing, wan, lang
shin » skin, sein, thin

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 yan guan hua rain ((yang jui) OR (pang jun)) ((wong sau) OR (((wong shiu) OR (song shin)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan guan hua rain ((yang jui) or (pang jun)) ((wong sau) or (((wong shiu) OR (song shin)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan guan hua rain ((yang jui) or (pang jun)) ((wong sau) or (((wong shiu) OR (song shin)))) ;*.
