Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung tuan » trung thanh, trung tam, tran tuan
bang cong » dang cong, bang song, hang cong
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
ban cong » van cong, phan cong, ban huong
tan toan » tan tran, tap toan, van toan
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 tuan ((ban cong) OR (bang cong)) tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - thanh trung tuan ((ban cong) or (bang cong)) tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - thanh trung tuan ((ban cong) or (bang cong)) tan toan cao*.
