Perhaps you should try some spelling variations:
kong saur » kong sar, kong siu, kong your
yan yang » yang yang, dan yang, tan yang
yao yang » yang yang
dam rein » dam region, am rhein, a rein
der rein » der rhein, der verein, der reinen
yang jin » yang jie, yang jun, ying jin
yang xi » yang di, yang yi, yang jui
wang » wing, wan, lang

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