Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh trang » thanh trung, canh tranh, hanh trinh
trang cua » tranh cua, tang cua, trung cua
cua tuong » cua truong, cua thuong, cua huong
ho chieu » theo chieu, hoc thieu, doi chieu
dong tac » cong tac, dong bac, dong tam
dong tai » dung tai, luong tai, cong tac
than cap » khan cap, thanh lap, thanh cac

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 trang cua tuong ((dong tac) OR (dong tai)) than cap~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh trang cua tuong ((dong tac) or (dong tai)) than cap*.
