Perhaps you should try some spelling variations:
chiet tach » chieu sach
thanh dung » thanh duong, thanh tung, thanh hung
phan hoang » pham hoang, phan hong, phan hoan
dung phan » dung nhan, dung luan, dung ha
ho chiet » ho chieu, ho thiet, hoc thiet
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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 tach - thanh dung phan hoang ((cong dan) OR (cong tan)) ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh dung phan hoang ((cong dan) OR (cong tan)) ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - thanh dung phan hoang ((cong dan) OR (cong tan)) ((than cau) or (than cap))*.
