Perhaps you should try some spelling variations:
sein kann » sein dann
yulu chen » yu chen
chen ming » cheng ming, chen ping, chan ming
yang july » yang judy, yang jun
ming jin » ying jin, min jin, ming qing
wang yue » wong yue, wang hua, wang yan
yang jui » yang judy, yang di, yang xi

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 OR doing) sein kann yulu chen ming jin ((wang yue) OR (((yang july) OR (yang jui)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(dong or doing) sein kann yulu chen ming jin ((wang yue) or (((yang july) OR (yang jui)))) ;~".
• Adding a wildcard symbol may retrieve word variants: (dong or doing) sein kann yulu chen ming jin ((wang yue) or (((yang july) OR (yang jui)))) ;*.
