Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hien ngan » hiem ngan, vien nganh, hien nhanh
tran tuan » tran xuan, tran quang, tran thanh
nong cong » tong cong, nang cong, dong cong
cong cong » cong dong, trong cong, dung cong
thanh chu » thanh chau, thanh cha, thanh thu
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 ngan - thanh tran tuan ((nong cong) OR (cong cong)) tan ((thanh chu) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien ngan - thanh tran tuan ((nong cong) OR (cong cong)) tan ((thanh chu) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien ngan - thanh tran tuan ((nong cong) OR (cong cong)) tan ((thanh chu) or (than cap))*.
