Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang liang, wang yanling
siew pei » siew hai, chew pei, siew ee
pei yang » wei yang, hui yang, pei yun
long du » long do, long run, long did
yang 3 » yang _, yang 8, gang 3
long d » long do, long _, long 2
mah » math

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