Perhaps you should try some spelling variations:
yang liang » wang liang, peng liang, yang guang
yan liang » wang liang, you liang, yan wang
yang yang » wang yang, wang yan
china has » china have, china how
has gang » has gone, das ganz, gai gang
long do » long d, long du, longer do
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 (yan liang))) OR (yang yang)) can china has gang 3 ((long do) OR (long did)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang liang) OR (yan liang))) or (yang yang)) can china has gang 3 ((long do) or (long did)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang liang) OR (yan liang))) or (yang yang)) can china has gang 3 ((long do) or (long did)) ;*.
