Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
hua brain » human brain, a brain, hua ban
brain han » brain gain, brain what, brain head
min dang » yimin dang, mein dank, ein dank
bin dann » sein dann, bin da, ein dank
dong di » dong sin

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 (wang yang))) OR (dong di)) ya hua brain han ((min dang) OR (bin dann)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) or (wang yang))) or (dong di)) ya hua brain han ((min dang) OR (bin dann)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) or (wang yang))) or (dong di)) ya hua brain han ((min dang) OR (bin dann)) hai ;*.
