Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
nhanh lang » nhanh quang, nhanh thang, nhan dang
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
te chinh » tai chinh
tac toan » tap toan, hach toan, tich toan
tam toan » tap toan, tam than, pham toan

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: te chinh sach - ((hanh tang) OR (nhanh lang)) cua nhung cong ((tac toan) OR (tam toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te chinh sach - ((hanh tang) or (nhanh lang)) cua nhung cong ((tac toan) OR (tam toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: te chinh sach - ((hanh tang) or (nhanh lang)) cua nhung cong ((tac toan) OR (tam toan)) tap*.
