Perhaps you should try some spelling variations:
risiko sharing » risk sharing
sharing oil » sharing our, sharing big, sharing his
der risiko » oder risiko, dem risiko, des risikos
long days » long day's, longer days, long way
yan gang » yan wang, yang guang, yang yang
hong hai » shang hai, zhong tai, dang hai
wan yan » wang yan, nan yan, wai yan

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: wan yan gang der risiko sharing oil ((hong hai) OR (long days)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan gang der risiko sharing oil ((hong hai) or (long days)) ;*.
