Perhaps you should try some spelling variations:
gong qiang » gong liutang
gong gang » hong gang, gongs gong, deng gang
zhang yan » zhang fan, zhang jian, wang yan
dan yang » daun yang, tan yang, wang yang
lang yan » wang yan, wang yang, yang yang
kann run » bank run, kann man, kann ein
un yang » daun yang, hui yang, tan yang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((lang yan) OR (zhang yan)) kann run ((dan yang) or (un yang)) lin ((gong gang) or (gong qiang)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (zhang yan)) kann run ((dan yang) OR (un yang)) lin ((gong gang) OR (gong qiang)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (zhang yan)) kann run ((dan yang) or (un yang)) lin ((gong gang) or (gong qiang)) ;".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (zhang yan)) kann run ((dan yang) or (un yang)) lin ((gong gang) or (gong qiang)) ;*.
