Perhaps you should try some spelling variations:
gender one » gender age, under one, gender off
gender die » gender age, gender d, gender das
wang yang » wang yan, wang liang, wang yanling
yang yan » yang yang, wang yan, yang fan
ii kein » iii kein, ii kern, ii kleine
yan ii » yan zi
kern » ken, bern, kerr

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 yang yan ii ((gender one) OR (gender die)) ((ii kein) OR (im kern)) (ghi OR ghia) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yan ii ((gender one) OR (gender die)) ((ii kein) or (im kern)) (ghi or ghia) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yan ii ((gender one) OR (gender die)) ((ii kein) or (im kern)) (ghi or ghia) ;*.
