Perhaps you should try some spelling variations:
gender age » gender wage, under age, gender a
die gender » die gelder, die genfer, life gender
yan wang » yuan wang, yang yang, qian wang
chan eng » chan fong, chan kang, chan ming
yang die » yang di, yang jie, klang die
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: ((yan wang) OR (chan eng)) yang die gender age ((ma kong) OR (ma rong)) (sar OR star) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (chan eng)) yang die gender age ((ma kong) OR (ma rong)) (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (chan eng)) yang die gender age ((ma kong) OR (ma rong)) (sar or star) ;*.
