Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung thanh » truong thanh
thuong dong » phuong dong, tuong dong, chuong dong
huong dong » phuong dong, chuong dong, tuong dong
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
toan cau » 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: ((ho trieu) OR (25 trieu)) tinh - thanh trung thanh ((huong dong) OR (thuong dong)) tinh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - thanh trung thanh ((huong dong) or (thuong dong)) tinh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - thanh trung thanh ((huong dong) or (thuong dong)) tinh toan cau*.
