Perhaps you should try some spelling variations:
host things » those things, last things, first things
things era » things here, things were, things a
main risk » chain risk
yan wang » yuan wang, yang yang, qian wang
yan risk » can risk, plan risk, than risk
dann bin » dong bin
dort ii » dort bin, dort hin

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: yan wang ((yan risk) OR (main risk)) host things era ((dong sin) OR (((dann bin) OR (dort ii)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan wang ((yan risk) OR (main risk)) host things era ((dong sin) or (((dann bin) or (dort ii)))) ;~".
• Adding a wildcard symbol may retrieve word variants: yan wang ((yan risk) OR (main risk)) host things era ((dong sin) or (((dann bin) or (dort ii)))) ;*.
