Perhaps you should try some spelling variations:
yulu cheng » yu cheng, yuan cheng
yulu chen » yu chen
chan fong » chew fong, chan eng, chan kang
fong wong » hong kong, hong jong, hong hong
yang yao » yang yang, wang yan, yang yi
yang fan » zhang fan, yang dean, yang yang
wong siu » wong shiu, kong siu, wong sau

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

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