Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
hanh manh » hanh mang, lanh manh, hoang manh
ho chieu » hoc thieu, doi chieu, mot chieu
manh cua » doanh cua, ban cua
cua dang » cua cong, cua ban
cong tap » cuong tap, cong tac, tong tap
cong tan » cong tac, cong san, cong thanh

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