Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, truong thanh
thong cong » trong cong, tong cong, thong thong
theo tien » theo tieu, thuc tien, theo tcvn
tien hanh » tien thanh, hien hanh, tien anh
tran tuan » tran xuan, tran quang, tran thanh
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tien hanh - thanh ((trung tuan) OR (tran tuan)) thong cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: theo tien hanh - thanh ((trung tuan) OR (tran tuan)) thong cong dan than cau*.
