Perhaps you should try some spelling variations:
thien thanh » thi thanh, hien hanh, chien tranh
thanh trung » thanh tung
hien nhanh » hien hanh, dien thanh, vien nganh
tien thanh » tien thinh, tran thanh, den thanh
trung van » truong van, trong van, trung va
dung cong » dung trong
van dung » van dong, xay dung, tin dung
cong san » cong tac
san toan » van toan, dan toan, manh toan
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 (((thien thanh) OR (tien thanh)))) - thanh trung van dung cong san toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) or (((thien thanh) OR (tien thanh)))) - thanh trung van dung cong san toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (((thien thanh) OR (tien thanh)))) - thanh trung van dung cong san toan cao*.
