Perhaps you should try some spelling variations:
wang liang » wang yang
yang yang » wang yang, wang yan
test ying » test using, test playing
ying jin » yang jin, jing ji, yang jie
long shu » cong shu, tong shui
long du » long d, long do, long run
a a » a la
dong » doing, done, hong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong sin) or (((wang liang) or (yang yang)))) a a test ying jin ((long shu) OR (long du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (((wang liang) OR (yang yang)))) a a test ying jin ((long shu) OR (long du)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (((wang liang) or (yang yang)))) a a test ying jin ((long shu) OR (long du)) ;".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (((wang liang) or (yang yang)))) a a test ying jin ((long shu) OR (long du)) ;*.
