Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yang guang » yang yang, yan guan
yan liang » wang liang, you liang, yan wang
tan chwee » tan khee, tan chinhwee
tan chew » tan cheng, tan siew, tan chia
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 liang))) or (yang guang)) ((tan chew) 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 liang))) OR (yang guang)) ((tan chew) 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 liang))) or (yang guang)) ((tan chew) or (tan chwee)) lei kyun a long do ;*".
