Perhaps you should try some spelling variations:
manh trung » manh tung, thanh trung, manh hung
hoc thieu » hoc hien
trung cua » truong cua, trung tuan, trung cap
dang cong » dung cong
cua dang » cua cong, cua ban
cong tac » cong ty
khan cap » khan ap, than cap, khoan cam

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 thieu) OR (toc thieu)) xanh - manh trung cua dang cong tac ((khan cap) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) xanh - manh trung cua dang cong tac ((khan cap) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) xanh - manh trung cua dang cong tac ((khan cap) or (phan tu))*.
