Perhaps you should try some spelling variations:
thanh trung » thanh tung
cong manh » duong manh, cong thanh, hoang manh
cong danh » cuong danh, cong dan, cong thanh
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
trung va » truong va, trang va, trung ha
va trong » va truong, va thong, va tuong
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 (30 trieu)) tinh - thanh trung va trong ((cong manh) OR (cong danh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - thanh trung va trong ((cong manh) or (cong danh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - thanh trung va trong ((cong manh) or (cong danh)) toan cao*.
