Perhaps you should try some spelling variations:
truong phuong » truong chung, truong trung, dung phuong
nhung phuong » dung phuong, nhu phuong, bang phuong
chieu sach » chinh sach, chiet tach, chieu sang
hanh trung » thanh trung, hanh trang, manh trung
trung cua » truong cua, trung tuan, trung cap
ho chieu » theo chieu, hoc thieu, doi chieu
phan cau » phan dau, phan cac, phan tu
khan cap » khan ap, than cap, khoan cam

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