Perhaps you should try some spelling variations:
yang liu » yang lin, yang di, yang xi
iii gang » ii gang, iii grand, ein gang
gang min » gong min, tang min, chang min
wong sau » wong sam, wong siu, wong shiu
yang li » yang lin, yang di, yang xi
wang » wing, wan, lang
scham » cham, schau

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 liu) OR (yang li)) iii gang min ((wong sau) OR (von scham)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang liu) OR (yang li)) iii gang min ((wong sau) or (von scham)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang liu) OR (yang li)) iii gang min ((wong sau) or (von scham)) ;*.
