Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
china hui » china hubei, china how, china han
china has » china have, china how
long do » long d, longer do, long ago
long du » long d, long run, long did
gang 3 » gang _, lang 3, wang 3

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 liang) OR (yang yang)) can ((china hui) OR (china has)) gang 3 ((long do) OR (long du)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yang yang)) can ((china hui) OR (china has)) gang 3 ((long do) or (long du)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang yang)) can ((china hui) OR (china has)) gang 3 ((long do) or (long du)) ;*.
