Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
than siew » tham siew, than anew, than she
tan siew » tham siew, mah siew, man sie
pei yang » wei yang, hui yang, pei yun
6.2 long » 3.2 long, 3.1 long
3 long » a long, 3.2 long, 3.1 long

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 guang)) ((than siew) OR (tan siew)) pei yang ((3 long) OR (6.2 long)) do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (yang guang)) ((than siew) OR (tan siew)) pei yang ((3 long) or (6.2 long)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang guang)) ((than siew) OR (tan siew)) pei yang ((3 long) or (6.2 long)) do ;*.
