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

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 (yan guan)) can child wen ((klang 3) OR (klang 31)) longer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yan guan)) can child wen ((klang 3) OR (klang 31)) longer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yan guan)) can child wen ((klang 3) OR (klang 31)) longer a ;*.
