Perhaps you should try some spelling variations:
thanh hung » thanh huong, thanh tung, thanh trung
hien manh » hien hanh, tien manh, hieu manh
dai phung » dai phong, tai phuong, mai phuong
dai khung » dai khong, dam khung, dai khoang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 manh - thanh hung ((dai phung) OR (dai khung)) ((cong dan) OR (cong tan)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: hoc hien manh - thanh hung ((dai phung) or (dai khung)) ((cong dan) or (cong tan)) toan cao*.
