Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
wang yang » wang liang, wang yanling
pei yang » wei yang, hui yang, yi yang
y.c long » 3.2 long, 3.1 long, 2.2 long
man sie » man die
pei yun » lei kyun, mei yung, wei yuan
long do » long d, long du, longer do

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)) man sie ((pei yun) OR (pei yang)) y.c long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) or (wang yan))) or (yang guang)) man sie ((pei yun) OR (pei yang)) y.c long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (wang yan))) or (yang guang)) man sie ((pei yun) OR (pei yang)) y.c long do ;*.
