Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung toan » truong toan, trung tuan, trung tran
thong cong » trong cong, tong cong, thong thong
thuc tien » thuc hien
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo tcvn) OR (thuc tien)) hanh - thanh trung toan thong cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: ((theo tcvn) or (thuc tien)) hanh - thanh trung toan thong cong dan than cau*.
