Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
wang yang » wang yan, wang liang, wang yanling
tan chwee » tan khee, tan chinhwee
chwee pei » chew pei
longer do » longer _, longer a, long do
yang y.c » yang yi, yang yao, yang 4.3
yang 47 » yang 4, yang 4.3

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: ((wang yang) OR (yang liang)) tan chwee pei ((yang 47) OR (yang y.c)) longer do ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang liang)) tan chwee pei ((yang 47) or (yang y.c)) longer do ;*.
