Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung cua » truong cua, trung tuan, trung cap
hang cong » dang cong, hang nong, bang cong
manh toan » thanh toan, anh tuan, tinh toan
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
toan ban » van ban

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: ((ho trieu) OR (25 trieu)) tinh - thanh trung cua ((hang cong) OR (trong cong)) manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - thanh trung cua ((hang cong) or (trong cong)) manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - thanh trung cua ((hang cong) or (trong cong)) manh toan ban*.
