Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
dong sind » dong sin, dong bin, dong ping
mein dank » ein dank, sein dann
lang yan » wang yan, wang yang, yang yang
hua rent » hua ren
rent yan » ren yan, rent a
min dang » yimin dang, bin dann, ein dank

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))) or (dong sind)) ya hua rent yan ((min dang) OR (mein dank)) hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((lang yan) OR (zhang yan))) OR (dong sind)) ya hua rent yan ((min dang) OR (mein dank)) hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((lang yan) or (zhang yan))) or (dong sind)) ya hua rent yan ((min dang) OR (mein dank)) hai ;*".
