Perhaps you should try some spelling variations:
nhung phuong » dung phuong, truong phuong, bang phuong
nhu phuong » thu phuong, thi phuong, thu huong
mot chieu » doi chieu
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
tranh ve » trinh ve, thanh ve, tranh va
toan cau » toan cao, toan ban, toan tap

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 (mot chieu)) xanh - canh tranh ve ((nhung phuong) OR (nhu phuong)) manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) xanh - canh tranh ve ((nhung phuong) OR (nhu phuong)) manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) xanh - canh tranh ve ((nhung phuong) OR (nhu phuong)) manh toan cau*.
