Perhaps you should try some spelling variations:
gan guan » yan guan, quan guan, fan guon
yan clan » das clan, yan guan, yan yuan
ii chang » vii chang, yi chang, ii changes
tan wong » tan hong, tan yong, t.j wong
tan kong » tan hong
yan tan » tan tan, yan guan, yan wang
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 tan) OR (yan clan))) OR (gan guan)) hsu ii chang ((tan wong) OR (tan kong)) yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan tan) or (yan clan))) or (gan guan)) hsu ii chang ((tan wong) OR (tan kong)) yue ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan tan) or (yan clan))) or (gan guan)) hsu ii chang ((tan wong) OR (tan kong)) yue ;*.
