Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
thanh lap » thanh san, phan lap, thanh hai
ho chiet » ho chieu, hoc thiet, hoa thiet
ho thiet » hoc thiet, hoa thiet, so thiet
cong dan » cong san, cong tan, huong dan
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: ((ho chiet) OR (ho thiet)) tach - thanh trung cua nhung cong dan ((than cau) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chiet) OR (ho thiet)) tach - thanh trung cua nhung cong dan ((than cau) or (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chiet) OR (ho thiet)) tach - thanh trung cua nhung cong dan ((than cau) or (thanh lap))*.
