Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
plus how » us how, bus how, plus new
dann war » wann war, da war, dann kam
dann hat » wann hat, dang hai, man hat
dong di » dong sin
how bin » how big, how bank, how bias
e a » et a
y a » y la

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: ((yang yang) OR (dong di)) ((e a) OR (y a)) plus how bin ((dann war) OR (dann hat)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (dong di)) ((e a) or (y a)) plus how bin ((dann war) or (dann hat)) ;*.
