Perhaps you should try some spelling variations:
doanh thanh » danh thanh, doanh nhan, dinh thanh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
thanh cua » tranh cua, than cua, hanh cua
cong dan » cong san, cong dong, cong tac
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: hoc chieu tinh - doanh thanh cua ban ((((cong dan) OR (huong dan))) OR (cong tan)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - doanh thanh cua ban ((((cong dan) or (huong dan))) or (cong tan)) toan ban*.
