Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, dan yang
yang yang » wang yang, wang yan
kong saur » kong sar, kong siu, kong your
der rein » der rhein, der verein, der reinen
dam rein » dam region, am rhein, a rein
yang jin » yang jie, yang jun, ying jin
jin kong » jin kang, jin song, king kong
di rein » i rein

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