Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
chieu sach » chinh sach, chiet tach, chieu sang
phuong dan » phuong danh, phuong doan, huong dan
doi chieu » doc hieu, doi chi, ho chieu
trung cua » truong cua, trung tuan, trung cap
mang cua » manh cua, dung cua, ban cua
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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