Perhaps you should try some spelling variations:
wang xueman » wang xuan
wang xiuyan » wang xinyan, wang xuan
china chang » chin chang, china changqi, china china
china zhang » cheng zhang, chin chang, china han
kong shiu » kong siu, wong shiu, kong eiu
ha kong » tan kong, ha huong, nan kong
yang 4 » yang 47, yang _, yang 8

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 xueman) OR (wang xiuyan)) yang 4 ((china chang) OR (china zhang)) ha kong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xueman) or (wang xiuyan)) yang 4 ((china chang) OR (china zhang)) ha kong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xueman) or (wang xiuyan)) yang 4 ((china chang) OR (china zhang)) ha kong shiu ;*.
