Perhaps you should try some spelling variations:
truong cua » truong ca, truong quan, truong cao
tran tuan » tran xuan, tran quang, tran thanh
bang cong » dang cong, bang song, hang cong
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
cong san » cong tac
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap

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 - hanh ((tran tuan) OR (truong cua)) bang cong san than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - hanh ((tran tuan) or (truong cua)) bang cong san than cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - hanh ((tran tuan) or (truong cua)) bang cong san than cau*.
