Perhaps you should try some spelling variations:
wang liang » wang yang
yang yang » wang yang, wang yan
out test » out west, about test, root test
out what » about what, get what
yang lin » yang jin, wang lin, yang liang
ling yue » li yue, ling xu, wang yue
yang li » yang di, yang xi, yang yi

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: ((yang yang) OR (wang liang)) wang ((out test) OR (out what)) ((yang lin) OR (yang li)) ling yue ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang liang)) wang ((out test) or (out what)) ((yang lin) or (yang li)) ling yue ;*.
