Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
sun gender » noun gender, von gender, human gender
gender age » gender wage, under age, gender a
wang yang » wang yan, wang liang, wang yanling
liang sun » liang dan, liang tan, wing sun
age latin » wage latin, large latin, wages latin
date sub » case sub, note sub
data sub » data set, data say, data s5
die spur » der spur

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 liang sun gender age latin ((((date sub) OR (data sub))) OR (die spur)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang liang sun gender age latin ((((date sub) OR (data sub))) or (die spur)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang liang sun gender age latin ((((date sub) OR (data sub))) or (die spur)) ;*.
