Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
yang yang » wang yang, wang yan
tan cheng » tang zheng, yuan cheng, tan hong
tan chwee » tan khee, tan chinhwee
tan chew » tan siew, tan chia, tan chor
lei kyun » lee kyung, lee kyu, pei yun
long do » long d, long du, longer do

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yan liang) or (yang yang)) ((((tan chew) OR (tan cheng))) or (tan chwee)) lei kyun a long do ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan liang) OR (yang yang)) ((((tan chew) OR (tan cheng))) OR (tan chwee)) lei kyun a long do ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang yang)) ((((tan chew) OR (tan cheng))) or (tan chwee)) lei kyun a long do ;*".
