Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
ming hua » ming hung, wang hua, ming lu
ying hua » wang hua, ying zhu, dong hua
yang hui » yang jui, wang hui, yang muxi
yang jin » yang jie, yang jun, ying jin
wong sau » wong sam, wong siu, wong shiu
shang » zhang, chang, sheng

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 ((((ming hua) OR (ying hua))) OR (yang hui)) irene ((shang jin) OR (yang jin)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((ming hua) OR (ying hua))) or (yang hui)) irene ((shang jin) or (yang jin)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((ming hua) OR (ying hua))) or (yang hui)) irene ((shang jin) or (yang jin)) wong sau ;*.
