Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh hinh » hanh chinh, hanh tinh, hanh dinh
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
hinh cua » chinh cua, sinh cua, tinh cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 xanh - hanh hinh cua nhung ((cong dan) OR (cong tan)) ((toan ban) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh hinh cua nhung ((cong dan) or (cong tan)) ((toan ban) or (toan cao))*.
