Perhaps you should try some spelling variations:
truong cong » trong cong, truong dong, truong long
doanh xuat » doanh luan, doanh cua, doanh bat
doan xuan » doan quan, doan tuan, doanh luan
30 trieu » 25 trieu
cong dan » cong san, cong tan, huong dan
cac cap » cao cap, cac cam, cac cay
cac cau » cac mau, bac cau, ca cau

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: 30 trieu tinh - hanh ((doan xuan) OR (doanh xuat)) truong cong dan ((cac cap) OR (cac cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "30 trieu tinh - hanh ((doan xuan) or (doanh xuat)) truong cong dan ((cac cap) OR (cac cau))~".
• Adding a wildcard symbol may retrieve word variants: 30 trieu tinh - hanh ((doan xuan) or (doanh xuat)) truong cong dan ((cac cap) OR (cac cau))*.
