Perhaps you should try some spelling variations:
yuan meng » juan meng, yuan ming, yuan cheng
meng yuan » meng hsuan, fang yuan, feng juan
yuan wang » yan wang, yuan kang, yuan chang
kong siu » kong eiu, wong siu, kong sar
wan yan » nan yan, wai yan, wang yang
ya yuan » yan yuan
sin » sign, sind, skin

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: ((((wan yan) OR (wang yan))) OR (dong di)) ya yuan meng yuan wang ((kong siu) OR (dong sin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) OR (wang yan))) or (dong di)) ya yuan meng yuan wang ((kong siu) or (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) OR (wang yan))) or (dong di)) ya yuan meng yuan wang ((kong siu) or (dong sin)) ;*.
