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

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 liang) OR (yang liang)) tan chwee pei ((yang 4.3) OR (yang y.c)) longer do ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang liang)) tan chwee pei ((yang 4.3) or (yang y.c)) longer do ;*.
