Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
how bias » home bias, how big, how bad
dong di » dong sin
how bin » how big, how bank, how bill
da war » das war, dann war, dead war
yet a » et a, yet _, get a
ye a » e a, me a, de a
y a » y la

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (dong di)) ((((ye a) OR (yet a))) or (y a)) bus ((how bin) or (how bias)) da war ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (dong di)) ((((ye a) OR (yet a))) OR (y a)) bus ((how bin) OR (how bias)) da war ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (dong di)) ((((ye a) OR (yet a))) or (y a)) bus ((how bin) or (how bias)) da war ;*".
