Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
yan yuan » yan guan, fang yuan, nan yan
hui ying » huei ying, hoi ying, hui ping
yi gang » ii gang, i gang, li gang
long do » long d, long du, longer do
3 long » a long, 2 long, 3.2 long

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