Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
hua gain » heat gain, run gain, hua ban
gain yan » gain a, nan yan
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
won sau » wong siu
yan ji » yan jiu, ban ji, pan ji

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang hyoung) or (wang yang)) wang hua gain yan ji ((((won sau) OR (wong sam))) or (wong sau)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang hyoung) OR (wang yang)) wang hua gain yan ji ((((won sau) OR (wong sam))) OR (wong sau)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hyoung) or (wang yang)) wang hua gain yan ji ((((won sau) OR (wong sam))) or (wong sau)) ;*".
