Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang yan, wang liang, wang yanling
mah chew » mah siew
pei yang » wei yang, hui yang, yi yang
pei yun » lei kyun, mei yung, wei yuan
long do » long d, long du, longer do
3 long » a long, 2 long, 3.2 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 yang) OR (yang guang)) mah chew ((pei yang) OR (pei yun)) 3 long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang guang)) mah chew ((pei yang) OR (pei yun)) 3 long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang guang)) mah chew ((pei yang) OR (pei yun)) 3 long do ;*.
