Perhaps you should try some spelling variations:
thanh trung » thanh tung
hien nhanh » hien hanh, thien thanh, tien thanh
trung tuan » trung thanh, trung tam, tran tuan
thong cong » trong cong, thong thong, phong chong
hien xanh » hien hanh, chieu xanh, hien khanh
tong cong » trong cong, cong cong, dung cong
tan toan » tan tran, tap toan, van toan
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 xanh) OR (hien nhanh)) - thanh trung tuan ((thong cong) OR (tong cong)) tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien nhanh)) - thanh trung tuan ((thong cong) OR (tong cong)) tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - thanh trung tuan ((thong cong) OR (tong cong)) tan toan tap*.
