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