Perhaps you should try some spelling variations:
risiko sharing » risk sharing
sharing oil » sharing our, sharing big, sharing his
die risiko » die risiken, das risiko, dem risiko
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
hong ghi » zhong zhi, hong g, hong hai
long ago » long arm
wang » wing, wan, lang

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 ((yan liang) OR (you liang)) die risiko sharing oil ((hong ghi) OR (long ago)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan liang) OR (you liang)) die risiko sharing oil ((hong ghi) or (long ago)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan liang) OR (you liang)) die risiko sharing oil ((hong ghi) or (long ago)) ;*.
