Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
tieu sach » chieu sach, dien sach, te sach
trinh cua » tinh cua, trinh luat, trinh quan
cong cong » cong dong, trong cong, dung cong
cong san » cong tac
toan cau » toan cao, toan tap
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban

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 tieu sach - hanh trinh cua cong cong san ((((toan cau) OR (toan tai))) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - hanh trinh cua cong cong san ((((toan cau) OR (toan tai))) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - hanh trinh cua cong cong san ((((toan cau) OR (toan tai))) or (toan ban))*.
