Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
doi chieu » doc hieu, doi chi, ho chieu
chinh van » chinh va, chinh ban, chinh can
dung cong » dung trong
danh toan » manh toan, dan toan, dang toan
van dung » van dong, xay dung, tin dung
anh toan » manh toan, anh tuan, thanh toan

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 (doi chieu)) xanh - hanh chinh van dung cong ((danh toan) OR (anh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (doi chieu)) xanh - hanh chinh van dung cong ((danh toan) OR (anh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (doi chieu)) xanh - hanh chinh van dung cong ((danh toan) OR (anh toan)) cao*.
