Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
nhung huong » nhung tuong, nhung cong, nhung dung
theo chieu » theo tieu, theo chu, thi chieu
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
ho chieu » hoc thieu, doi chieu, mot chieu
tinh cua » trinh cua, sinh cua, tinh chat
anh luan » anh tuan, anh quan, anh xuan

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)) tinh - nhanh tinh cua ((nhung huong) OR (nhung phuong)) anh luan van~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) tinh - nhanh tinh cua ((nhung huong) OR (nhung phuong)) anh luan van~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) tinh - nhanh tinh cua ((nhung huong) OR (nhung phuong)) anh luan van*.
