Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, dong jung
yang yang » wang yang, wang yan
dan yang » daun yang, tan yang, wang yang
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
hua dan » hua ban
yang hu » yang hui, gang hu, yang du
yi hua » li hua, ya hua, yi hui

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: ((dong yang) OR (yang yang)) yi hua dan yang hu ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (yang yang)) yi hua dan yang hu ((hong ghi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) OR (yang yang)) yi hua dan yang hu ((hong ghi) or (hong hai)) ;*.
