Perhaps you should try some spelling variations:
dam region » das region, der region, die region
kong saur » kong sar, kong siu, kong your
yan yang » yang yang, yao yang, dan yang
dam rein » am rhein, der rein, a rein
yang jui » yang judy, yang di, yang xi
yang yi » yang di, yang xi
wang » wing, wan

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 OR lang) yan yang ((dam rein) OR (dam region)) ((yang jui) OR (yang yi)) kong saur ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR lang) yan yang ((dam rein) or (dam region)) ((yang jui) or (yang yi)) kong saur ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR lang) yan yang ((dam rein) or (dam region)) ((yang jui) or (yang yi)) kong saur ;*.
