Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
hua brain » a brain, hua ban
our brain » your brain, our brains, our main
tin hong » tan hong, kia hong, thi hong
hong ghi » zhong zhi, hong g, hong hai
dong di » dong sin
han tin » han min

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: ((wang yang) OR (dong di)) ya ((((hua brain) OR (our brain))) OR (human brain)) han tin hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (dong di)) ya ((((hua brain) OR (our brain))) or (human brain)) han tin hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (dong di)) ya ((((hua brain) OR (our brain))) or (human brain)) han tin hong ghi ;*.
