Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
chieu sach » chinh sach, chiet tach, chieu sang
doi chieu » doc hieu, doi chi, ho chieu
truong va » truong cao, truong dao, luong va
dan chan » dan gian, dan ca, van chat
dan can » dan canh, dan ca, ban can

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sach - manh ((truong va) or (truong dai)) nhung tuong ((dan can) OR (dan chan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - manh ((truong va) OR (truong dai)) nhung tuong ((dan can) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - manh ((truong va) or (truong dai)) nhung tuong ((dan can) OR (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - manh ((truong va) or (truong dai)) nhung tuong ((dan can) OR (dan chan)) cau*.
