Perhaps you should try some spelling variations:
chiet tach » chieu sach
trung tuan » trung thanh, trung tam, tran tuan
trung cua » truong cua, trung cap, dung cua
ho chiet » ho chieu, ho thiet, hoc thiet
tung cua » tuong cua, dung cua, tang cua
cong tan » cong tac, cong san, cong thanh
tan can » toan can, tan van, ban can
can cau » van cau, ban cau, ca cau

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 ((tung cua) OR (((trung cua) OR (trung tuan)))) trong cong tan can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh ((tung cua) or (((trung cua) OR (trung tuan)))) trong cong tan can cau~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - thanh ((tung cua) or (((trung cua) OR (trung tuan)))) trong cong tan can cau*.
