Perhaps you should try some spelling variations:
manh trung » manh tung, thanh trung, manh hung
nhung cong » dung cong, thong cong, hang cong
hoc chinh » hoan chinh, hoc sinh, hoc kinh
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac
khan ap » khan cap, han ap, khan dam

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 chinh sach - manh trung cua nhung cong san ((khan ap) OR (than cap))~.
• Adding a wildcard symbol may retrieve word variants: hoc chinh sach - manh trung cua nhung cong san ((khan ap) or (than cap))*.
