Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wan ming » kian ming, chan ming, yuan ming
cong sun » cong shu, wing sun
cong van » congo can, duong van
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
li wan » li wang, li lan, li nan

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan daud ((((yang li) or (yang liang))) or (yang xi)) li wan ming ((cong sun) OR (cong van)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan daud ((((yang li) OR (yang liang))) OR (yang xi)) li wan ming ((cong sun) OR (cong van)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan daud ((((yang li) or (yang liang))) or (yang xi)) li wan ming ((cong sun) OR (cong van)) ;*".
