Perhaps you should try some spelling variations:
wang xiuyan » wang xinyan, wang xuan
china zhang » china chang, cheng zhang, china han
wang yuhan » wang luhang, wang yan, wang yidan
chin chang » china chang, chain change, colin chang
tan kong » tan hong
kong siu » kong eiu, wong siu, dong sin
gang 3 » gang _, lang 3, wang 3

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 yuhan) OR (wang xiuyan)) gang 3 ((chin chang) OR (china zhang)) tan kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuhan) or (wang xiuyan)) gang 3 ((chin chang) OR (china zhang)) tan kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuhan) or (wang xiuyan)) gang 3 ((chin chang) OR (china zhang)) tan kong siu ;*.
