Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, hanh trang, danh trung
manh trung » manh tung, thanh trung, manh hung
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac
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 xanh - ((hanh trung) OR (manh trung)) cua ban ((cong tan) OR (cong san)) tran ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trung) or (manh trung)) cua ban ((cong tan) OR (cong san)) tran ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trung) or (manh trung)) cua ban ((cong tan) OR (cong san)) tran ban*.
