Perhaps you should try some spelling variations:
thien chinh » tien thinh, thien chien, thi chinh
cua thang » cua hang, cua thanh, xua thang
hanh ban » thanh ban, hang ban, hanh san
long dan » long doan, cong dan, long van
nong dan » cong dan, nong san, nguong dan
toan cao » toan ban, toan tap
ban cua » ban quan

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: thien chinh sach - hanh ban cua thang ((long dan) OR (nong dan)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: thien chinh sach - hanh ban cua thang ((long dan) or (nong dan)) toan cao*.
