Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
hang cong » dang cong, hang nong, bang cong
ho chieu » hoc thieu, doi chieu, mot chieu
chinh ca » chinh ta, chinh va, chinh tai
cong san » cong tac
toan tap » toan ban
ca hang » cua hang, ca chang, va hang
han tap » han tai, nhan tai, nhan tao

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 chinh ca hang cong san ((han tap) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - hanh chinh ca hang cong san ((han tap) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - hanh chinh ca hang cong san ((han tap) or (toan tap))*.
