Perhaps you should try some spelling variations:
wang wei » zhang wei, wang zhi
wei dann » sein dann, wenn dann, wei aun
dann can » dann bin, dan cao, dann hat
can when » can women, can we, can win
yang jui » yang judy, yang yi
when so » when do, when co, when soft
yang xi » yang yi

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: wang wei dann can when so ein ((yang jui) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang wei dann can when so ein ((yang jui) or (((yang di) or (yang xi)))) ;*.
