Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng, yuan ming
lang yan » wang yan, wang yang, zhang yan
yan clan » das clan, yan guan, yan yuan
hua rene » hua ren, juan rene
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
wong sau » wong sam, wong siu, wong shiu

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan clan ((hua rene) OR (juan meng)) ((yang jin) OR (yang jun)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan clan ((hua rene) OR (juan meng)) ((yang jin) OR (yang jun)) wong sau ;*.
