Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
bias dann » bin dann
how bias » home bias, how big, how bad
dann war » wann war, da war, dann hat
bus how » bust how, us how, plus how
me a » m a, me _, e a
y a » y la
sin » sign, sind, skin

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) OR (dong sin)))) ((me a) OR (y a)) bus how bias dann war ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (((dong di) OR (dong sin)))) ((me a) or (y a)) bus how bias dann war ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (((dong di) OR (dong sin)))) ((me a) or (y a)) bus how bias dann war ;*.
