Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, theo chu, thi chieu
trung tham » trung tam, trung thanh, trung thang
tham thong » pham thuong, than thuong, thoai thong
thong cong » trong cong, tong cong, thong thong
ho chieu » hoc thieu, doi chieu, mot chieu
cong dan » cong san, cong tan, huong dan
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 chieu) OR (theo chieu)) sach - thanh trung tham thong cong dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sach - thanh trung tham thong cong dan ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) sach - thanh trung tham thong cong dan ((than cau) or (than cap))*.
