Perhaps you should try some spelling variations:
sein dann » sein kann, sein das, ein dank
yulu chen » yu chen
chen ying » chen yang, chen ping, chen jing
bin dann » bin da, ein dank
ying jin » yang jin, jing ji, yang jie
wang yue » wong yue, wang hua, wang yan
yang yi » yang xi, yang jui

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: dong ((bin dann) OR (sein dann)) yulu chen ying jin ((((wang yue) OR (yang yi))) OR (yang di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((bin dann) OR (sein dann)) yulu chen ying jin ((((wang yue) or (yang yi))) or (yang di)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((bin dann) OR (sein dann)) yulu chen ying jin ((((wang yue) or (yang yi))) or (yang di)) ;*.
