Perhaps you should try some spelling variations:
chiet tach » chieu sach
nhung cong » dung cong, thong cong, hang cong
doi chiet » doi chieu, doi chi, doi viet
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
toan cau » toan cao, toan ban, toan tap
ty toan » ly toan, tap toan, huy toan

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chiet tach - ((hanh tang) OR (hanh mang)) cua nhung cong ty toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi chiet tach - ((hanh tang) OR (hanh mang)) cua nhung cong ty toan cau*.
