Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
can child » care child, can build, can china
child wen » child went, child when, child well
langer do » longer do, langer _
klang 3 » klang 31, klang _, klange _
lang 3 » gang 3, lang _, lang a

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (yang guang)) can child wen ((lang 3) OR (klang 3)) langer do ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yang guang)) can child wen ((lang 3) OR (klang 3)) langer do ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang guang)) can child wen ((lang 3) OR (klang 3)) langer do ;*".
