Perhaps you should try some spelling variations:
thi chieu » thi chien, thi hieu, theo chieu
tranh cua » doanh cua, manh cua
ho chieu » theo chieu, hoc thieu, doi chieu
cua tong » cua cong, cua dong, cua nong
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan ban » van 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 (thi chieu)) xanh - canh tranh cua tong ((cong dan) OR (cong san)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chieu)) xanh - canh tranh cua tong ((cong dan) OR (cong san)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chieu)) xanh - canh tranh cua tong ((cong dan) OR (cong san)) toan ban*.
