Perhaps you should try some spelling variations:
thien chinh » tien thinh, thien chien, thi chinh
hanh manh » hanh mang, lanh manh, hoang manh
xua thang » xuan thang, xuan thanh, xuan trang
long doan » cong doan, dong doanh, rong doanh
manh xua » manh cua, minh xua, manh tuan
nong dan » cong dan, nong san, nguong dan
toan cao » toan ban, toan tap

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