Perhaps you should try some spelling variations:
rein gang » ein gang, ein ganz, den gang
ban kong » tan kong, nan kong, bank long
ban nong » bank long, ban nor, can non
der rein » der rhein, der verein, der reinen
wong sam » wong sau, wong lai, kong sar
wong yue » wang yue, hong yu
gang li » gan li, tang li, wang li

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 ((ban kong) OR (ban nong)) der rein gang li ((wong sam) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ban kong) OR (ban nong)) der rein gang li ((wong sam) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ban kong) OR (ban nong)) der rein gang li ((wong sam) or (wong yue)) ;*.
