Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
quan duong » tuan duong, quan dong, qua duong
duong cong » dung cong, luong cong, duong trong
doi chieu » doc hieu, doi chi, mot chieu
ho chieu » theo chieu, hoc thieu, mot chieu
cong tac » cong ty
tac than » tac thanh, tam than, tac nhan
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: ((doi chieu) OR (ho chieu)) xanh - ((hanh trinh) OR (anh huong)) quan duong cong tac than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) xanh - ((hanh trinh) or (anh huong)) quan duong cong tac than cap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) xanh - ((hanh trinh) or (anh huong)) quan duong cong tac than cap*.
