Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
doi chieu » doc hieu, doi chi, ho chieu
manh toan » thanh toan, anh tuan, tinh toan
dan toan » van toan, dan than, xuan toan

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: doi chieu xanh - hanh ((truong cua) OR (truong cao)) nhung tuong ((dan toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - hanh ((truong cua) OR (truong cao)) nhung tuong ((dan toan) or (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh ((truong cua) OR (truong cao)) nhung tuong ((dan toan) or (manh toan)) cau*.
