Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang yanling
siew pei » siew hai, chew pei, siew ee
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
tham » than, them, cham

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 (wang yang))) OR (yang guang)) tham 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 (wang yang))) or (yang guang)) tham siew pei yang ((3 long) or (6.2 long)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) OR (wang yang))) or (yang guang)) tham siew pei yang ((3 long) or (6.2 long)) do ;*.
