Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
tuan china » wuhan china, can china, taiwan china
yan liang » wang liang, you liang, yan wang
china has » china have, china how
longer do » longer _, longer a, long do
has lang » das lange, das land, has bank
3 longer » _ longer, 2 longer, 3 langer
lang 3 » klang 3, gang 3, lang _

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 liang))) OR (wang yan)) tuan china has lang 3 longer do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan liang) OR (yang liang))) or (wang yan)) tuan china has lang 3 longer do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yan liang) OR (yang liang))) or (wang yan)) tuan china has lang 3 longer do ;*.
