Perhaps you should try some spelling variations:
dean rein » der rein
gang yao » yang yao, wang yan, ganga ya
yao yang » yang yang
dam rein » dam region, am rhein, der rein
yang jie » yang jin, yang jui, yang yi
kong siu » kong eiu, wong siu, dong sin
yang xi » yang yi, 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: gang yao yang ((dean rein) OR (dam rein)) ((((yang jie) OR (yang di))) OR (yang xi)) kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gang yao yang ((dean rein) OR (dam rein)) ((((yang jie) or (yang di))) or (yang xi)) kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: gang yao yang ((dean rein) OR (dam rein)) ((((yang jie) or (yang di))) or (yang xi)) kong siu ;*.
