Perhaps you should try some spelling variations:
first kann » first kind
one first » come first, one fast, one fits
kann doch » dann doch, kann ich, kann sich
doch chen » goh chen, don chen
yang jui » yang judy, yang xi
wong yue » wang yue, hong yu
yang yi » yang xi

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: one first kann doch chen ((((yang jui) OR (dong sin))) OR (yang yi)) ((wong yue) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one first kann doch chen ((((yang jui) or (dong sin))) or (yang yi)) ((wong yue) or (yang di)) ;*.
