Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
our best » your best, hr best, our bit
der best » der besitz
kong sek » kong weak, kong sar, kong lee
song von » doing von, song jin, song min
yan tan » tan tan, yan clan, yan guan
kong k » kong _, kong a, king k

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: lang yan tan ((our best) OR (der best)) human brain ((((kong sek) OR (kong k))) OR (song von)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan tan ((our best) OR (der best)) human brain ((((kong sek) or (kong k))) or (song von)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan tan ((our best) OR (der best)) human brain ((((kong sek) or (kong k))) or (song von)) ;*.
