Perhaps you should try some spelling variations:
hien nhanh » thien thanh, tien thanh, dien thanh
hien hanh » dieu hanh
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
hinh sinh » tinh sinh, hinh dinh, hinh kinh
dang cong » dung cong
cua dang » cua cong, cua ban
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan cau » toan cao, toan ban, toan tap

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: hoc ((hien nhanh) OR (hien hanh)) - ((hanh tinh) OR (hinh sinh)) cua dang cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) OR (hien hanh)) - ((hanh tinh) or (hinh sinh)) cua dang cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) OR (hien hanh)) - ((hanh tinh) or (hinh sinh)) cua dang cong san toan cau*.
