Perhaps you should try some spelling variations:
risiko sharing » risk sharing
sharing oil » sharing our, sharing big, sharing his
dem risiko » der risiko, des risikos, oder risiko
wang yong » wang yang, wang hyoung, wang yan
liang dem » liang dan, liang wei
long days » long day's, longer days, long way
wang you » want you, chang you, wants you
hong ghi » zhong zhi, hong g, hong hai

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