Perhaps you should try some spelling variations:
yulu chen » yu chen
chan ming » kian ming, chan eng, chan fong
yang yao » yang yang, wang yan, yang yi
yu cheng » yu chen, _ cheng
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew
yan yao » gang yao, yan yuan

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang ((yan yao) or (yang yao)) ((yulu chen) or (yu cheng)) chan ming ((kong siu) OR (wong siu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((yan yao) OR (yang yao)) ((yulu chen) OR (yu cheng)) chan ming ((kong siu) OR (wong siu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan yao) or (yang yao)) ((yulu chen) or (yu cheng)) chan ming ((kong siu) OR (wong siu)) ;".
• Adding a wildcard symbol may retrieve word variants: lang ((yan yao) or (yang yao)) ((yulu chen) or (yu cheng)) chan ming ((kong siu) OR (wong siu)) ;*.
