Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
thanh tran » thanh trang, thanh toan, thanh tra
tuan khong » toan khong, tuan phong, thuan phong
khong cong » thong cong, khong cang, chong cong
hien xanh » hien hanh, chieu xanh, hien khanh
tran tuan » tran xuan, tran quang, tran thanh
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: hoc ((hien xanh) OR (hien nhanh)) - thanh tran tuan khong cong ((tac toan) OR (tam toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien nhanh)) - thanh tran tuan khong cong ((tac toan) OR (tam toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - thanh tran tuan khong cong ((tac toan) OR (tam toan)) tap*.
