Perhaps you should try some spelling variations:
thanh tung » thanh cong
theo tien » theo tieu, thuc tien, theo tcvn
tien hanh » tien thanh, hien hanh, tien anh
tung cua » trung cua, tuong cua, dung cua
cong dan » cong san, cong tan, cong dong
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu

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: theo tien hanh - thanh tung cua ban ((cong dan) OR (huong dan)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tien hanh - thanh tung cua ban ((cong dan) or (huong dan)) ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo tien hanh - thanh tung cua ban ((cong dan) or (huong dan)) ((than cau) OR (phan cau))*.
