Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
dang cong » dung cong
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, mot chieu
tinh cua » trinh cua, sinh cua, tinh chat
ban cong » bang cong, phan cong, ban huong
van cong » van dong, van phong, phan cong
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 sach - hanh tinh cua ((((ban cong) OR (dang cong))) OR (van cong)) manh toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh tinh cua ((((ban cong) or (dang cong))) or (van cong)) manh toan cao*.
