Perhaps you should try some spelling variations:
thien thanh » tien thanh, thi thanh, hien hanh
doan thien » hoan thien, doan thi, toan thiet
nhung cong » dung cong, thong cong, hang cong
chinh va » chinh ta, chinh tai, hanh va
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao
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: doan thien thanh - hanh chinh va nhung cong dan ((toan tai) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: doan thien thanh - hanh chinh va nhung cong dan ((toan tai) or (toan ban))*.
