Perhaps you should try some spelling variations:
zhang ming » zhang xin
kang minah » sang minh
chang mae » chang ha, changes made
yan yang » yang yang, yao yang, dan yang
wong sau » wong sam, wong siu, wong shiu
li li » li lin, li l, li yi
li lu » li ju, li l, li wu
wang » wing, wan, lang

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 yang ((li li) OR (li lu)) ((kang minah) OR (((chang mae) OR (zhang ming)))) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang ((li li) OR (li lu)) ((kang minah) or (((chang mae) or (zhang ming)))) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang ((li li) OR (li lu)) ((kang minah) or (((chang mae) or (zhang ming)))) wong sau ;*.
