Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
hanh trang » thanh trung, canh tranh, hanh trinh
chua xang » chua nang, chuc nang, chu bang
ho chieu » hoc thieu, doi chieu, mot chieu
cong tan » cong tac, cong san, cong thanh
tran ban » tranh ban, tran van, toan ban

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