Perhaps you should try some spelling variations:
thanh trung » thanh tung
hoc thieu » hoc hien
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong toan » cong tan, cong hoan, cong doan
cong tuan » cong tan, cong luan, cong thanh
thanh lap » thanh san, phan lap, thanh hai

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)) danh - thanh trung cua nhung ((cong toan) OR (cong tuan)) thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) danh - thanh trung cua nhung ((cong toan) or (cong tuan)) thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) danh - thanh trung cua nhung ((cong toan) or (cong tuan)) thanh lap*.
