Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
hai fang » cai fang, kai fang, hai anh
long do » long du, longer do, long ago
fang a » fang _, lang a, facing a
long d » long du, long _, long 2
mah » math
siew » view, sie

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