Perhaps you should try some spelling variations:
east frisian » east frisia, coast frisian, west frisian
frisian than » frisian town, frisian law
wang liang » wang yang
dong sign » dong sin, among sign
dong bin » dong sin, dong di, dann bin
daem hai » dang hai
a far » a fair, a farm, _ far

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 liang) OR (((dong sign) OR (dong bin)))) a far east frisian than ((daem hai) OR (dem hi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (((dong sign) or (dong bin)))) a far east frisian than ((daem hai) OR (dem hi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (((dong sign) or (dong bin)))) a far east frisian than ((daem hai) OR (dem hi)) ;*.
