Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
can child » care child, can build, can china
child wen » child went, child when, child well
longer do » longer _, longer a, long do
yang 3 » yang _, yang 8, lang 3
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: ((yan liang) OR (yang guang)) can child wen ((yang 3) OR (gang 3)) longer do ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) can child wen ((yang 3) or (gang 3)) longer do ;*.
