Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng
yuan ming » yuan ting, kian ming, tuan minh
lang yan » wang yan, wang yang, zhang yan
yan yuan » yan guan, fang yuan, nan yan
yang jui » yang judy, yang xi
wong siu » wong shiu, kong siu, wong sau
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: lang yan yuan ((juan meng) OR (yuan ming)) ((yang yi) OR (((yang jui) OR (yang di)))) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yuan ((juan meng) OR (yuan ming)) ((yang yi) or (((yang jui) or (yang di)))) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yuan ((juan meng) OR (yuan ming)) ((yang yi) or (((yang jui) or (yang di)))) wong siu ;*.
