Perhaps you should try some spelling variations:
guan yuan » gan guan, quan guan, yan yuan
yuan ming » yuan ting, kian ming, tuan minh
yan guan » gan guan, yan yuan, yang guang
yang jui » yang xi
wong siu » wong shiu, kong siu, wong sau
nan yan » nan ya, wang yan, qian yan
yang yi » yang xi

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: nan yan guan yuan ming ((((yang jui) OR (yang di))) OR (((yang judy) OR (yang yi)))) wong siu ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan guan yuan ming ((((yang jui) or (yang di))) or (((yang judy) or (yang yi)))) wong siu ;*.
