Perhaps you should try some spelling variations:
thien thanh » tien thanh, thi thanh, chien tranh
thanh trung » thanh tung
hien nhanh » tien thanh, dien thanh, vien nganh
dang trong » dung trong, dong trong, lang trong
hien hanh » dieu hanh
trung cua » truong cua, trung tuan, trung cap
trong tap » trong thap, tong tap, trong tan
cua dang » cua cong, cua ban
tap doan » tap quan
doan cau » toan cau, doan dau, doan cap

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 (hien hanh))) OR (thien thanh)) - thanh trung cua dang trong tap doan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((((hien nhanh) or (hien hanh))) or (thien thanh)) - thanh trung cua dang trong tap doan cau*.
