Perhaps you should try some spelling variations:
cong nguong » cong nguon, cong thuong, cong luong
hanh tang » hanh trang, anh tang, hanh mang
dan chinh » dang chinh, lan chinh, van chinh
dang hinh » bang hinh, dang dinh, dang hanh
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
tang cua » mang cua, hang cua, tang luan

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 tang cua cong nguong ((dan chinh) OR (dang hinh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - hanh tang cua cong nguong ((dan chinh) or (dang hinh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - hanh tang cua cong nguong ((dan chinh) or (dang hinh)) cau*.
