Perhaps you should try some spelling variations:
phuong danh » phuong anh, phuong dinh, phuong hanh
theo chieu » theo tieu, theo chu, thi chieu
hanh tang » hanh trang, anh tang, hanh mang
danh toan » manh toan, anh toan, dan toan
ho chieu » hoc thieu, doi chieu, mot chieu
va duong » van duong, va tuong, va huong
toan cau » toan cao, toan ban, toan tap
va dung » van dung, vat dung, va ung

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: ((ho chieu) OR (theo chieu)) xanh - hanh tang ((va dung) OR (va duong)) phuong danh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - hanh tang ((va dung) OR (va duong)) phuong danh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - hanh tang ((va dung) OR (va duong)) phuong danh toan cau*.
