Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, dien thanh
tien thanh » tien thinh, tran thanh, den thanh
thanh hang » thanh hoang, thanh thang, tranh hang
cong cong » cong dong, trong cong, dung cong
hang cua » mang cua, hang ca, huong cua
cong ban » cong bang, cong san, cong tan
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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 (tien thanh)) - thanh hang cua cong cong ban ((than cau) OR (than cap))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (tien thanh)) - thanh hang cua cong cong ban ((than cau) or (than cap))*.
