Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
nhung cong » dung cong, thong cong, hang cong
tranh cua » doanh cua
ho chieu » hoc thieu, doi chieu, mot chieu
manh cua » doanh cua, ban cua
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cau » toan cau, phan cau, than cap

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: ((theo chieu) OR (ho chieu)) sach - hanh ((tranh cua) OR (manh cua)) nhung cong tan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) sach - hanh ((tranh cua) OR (manh cua)) nhung cong tan than cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) sach - hanh ((tranh cua) OR (manh cua)) nhung cong tan than cau*.
