Perhaps you should try some spelling variations:
fang yuan » wang yuhan, wang yan, meng yuan
zheng kie » zheng he
zheng liu » zheng lili, cheng lu, heng li
yan clan » das clan, yan guan, yan yuan
wong siu » wong shiu, kong siu, wong sau
nan yan » nan ya, wang yan, qian yan
li chen » yi chen, jui chen
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 clan) OR (fang yuan))) OR (nan yan)) li chen ((zheng kie) OR (zheng liu)) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan clan) or (fang yuan))) or (nan yan)) li chen ((zheng kie) OR (zheng liu)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan clan) or (fang yuan))) or (nan yan)) li chen ((zheng kie) OR (zheng liu)) wong siu ;*.
