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

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