Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
china wang » china chang, china zhang, china won
china yang » china ying, china chang, china zhang
yan liang » yang liang, wang liang, you liang
2 longer » _ longer, 3 longer, a longer
longer a » longer _
yang 2 » yang _, yang 8, yang 4

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: ((yan liang) OR (yang guang)) can ((china wang) OR (china yang)) yang 2 longer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang guang)) can ((china wang) OR (china yang)) yang 2 longer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) can ((china wang) OR (china yang)) yang 2 longer a ;*.
