Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
dong der » ding der, dong di, dong wei
der bank » der banken
yang jie » yang jin, yang jui, yang yi
when so » when do, when co, when soft
so ming » so fing, so ging, su ming
yang xi » yang yi, yang jui
bank i » bank ii, bank im, bank _
i when » ii when, 3 when, 4 when

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 der bank i when so ming ((((yang yang) OR (yang jie))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong der bank i when so ming ((((yang yang) or (yang jie))) or (((yang di) or (yang xi)))) ;*.
