Perhaps you should try some spelling variations:
klarung des » klarung der, erklarung des, aufklarung des
gender age » gender wage, under age, gender a
yuan wang » yan wang, yuan kang, yuan chang
chan eng » chan fong, chan kang, chan ming
under a » under _
ma kong » ma hong, tan kong, nan kong
ma rong » ma hong

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: ((yuan wang) OR (chan eng)) klarung des ((gender age) OR (under a)) ((ma kong) OR (ma rong)) sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan wang) or (chan eng)) klarung des ((gender age) or (under a)) ((ma kong) OR (ma rong)) sar ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan wang) or (chan eng)) klarung des ((gender age) or (under a)) ((ma kong) OR (ma rong)) sar ;*.
