Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
dong sink » dong sin, dong bin, dong ping
dong sign » dong sin, among sign, dong bin
yan than » van thanh, yan zhang, yan clan
hong shu » cong shu, tong shui, wong shiu
hong ghi » zhong zhi, hong g, hong hai
hua ren » hua chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong yang) or (((dong sink) or (dong sign)))) ya hua ren yan than ((hong shu) OR (hong ghi)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (((dong sink) OR (dong sign)))) ya hua ren yan than ((hong shu) OR (hong ghi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (((dong sink) or (dong sign)))) ya hua ren yan than ((hong shu) OR (hong ghi)) ;".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) or (((dong sink) or (dong sign)))) ya hua ren yan than ((hong shu) OR (hong ghi)) ;*.
