Perhaps you should try some spelling variations:
yulu chen » yu chen
chen wang » chen yang, chen rong, chen ping
sind das » und das, sind die, wird das
wang hui » wang hua, wang zhi, wang wei
yang yue » yang yun, yang jui, yang yi
wang yue » wong yue, wang hua, wang yan
sin da » bin da, sein das
dong » doing, long, done

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 ((sin da) OR (sind das)) yulu chen wang hui ((yang yue) OR (wang yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((sin da) OR (sind das)) yulu chen wang hui ((yang yue) or (wang yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((sin da) OR (sind das)) yulu chen wang hui ((yang yue) or (wang yue)) ;*.
