Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
can wheat » corn wheat, can when, can beat
yang yang » wang yang, wang yan
dang hadi » dang hai
wenn man » kann man, wenn das
yang jin » yang jie, yang jun, ying jin
man can » man han, woman can, man kann

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

• Performing a fuzzy search may retrieve terms with similar spellings: wenn man can wheat grains ((((yang liang) OR (yang yang))) or (yang jin)) dang hadi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wenn man can wheat grains ((((yang liang) OR (yang yang))) OR (yang jin)) dang hadi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn man can wheat grains ((((yang liang) OR (yang yang))) or (yang jin)) dang hadi ;*".
