Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
nhung cong » dung cong, thong cong, hang cong
lanh manh » lanh tranh, lan anh, van manh
cua nhung » va nhung
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
manh cua » doanh cua, ban cua
toan cao » toan tap
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 (30 trieu)) tinh - lanh manh cua nhung cong thanh ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - lanh manh cua nhung cong thanh ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - lanh manh cua nhung cong thanh ((toan cao) or (toan ban))*.
