Perhaps you should try some spelling variations:
hien nhanh » thien thanh, tien thanh, dien thanh
cua truong » xuan truong, cac truong, xa truong
phuong van » phung van, phong van, phuong lan
hien hanh » dieu hanh
cua trung » xuan trung, cua nhung, ba trung
van toan » van tuan, van tan, van thanh
toan tap » toan 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: hoc ((hien nhanh) OR (hien hanh)) - canh tranh ((cua truong) OR (cua trung)) phuong van toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) or (hien hanh)) - canh tranh ((cua truong) OR (cua trung)) phuong van toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (hien hanh)) - canh tranh ((cua truong) OR (cua trung)) phuong van toan tap*.
