Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
tan chwee » tan khee, tan chinhwee
longer do » longer _, longer a
you xian » you liang, you can, you mean
tan chew » tan cheng, tan siew, tan chia
lei kyun » lee kyung, lee kyu, pei yun
long do » long d, long du, long ago

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((you xian) OR (yang guang)) ((tan chew) OR (tan chwee)) lei kyun a ((long do) OR (longer do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((you xian) or (yang guang)) ((tan chew) or (tan chwee)) lei kyun a ((long do) OR (longer do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((you xian) or (yang guang)) ((tan chew) or (tan chwee)) lei kyun a ((long do) OR (longer do)) ;*.
