Perhaps you should try some spelling variations:
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
cuong tap » luong tap, cong tac, luong tai
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
tang cua » mang cua, hang cua, tang luan
cong tap » cong tac, cong tan, tong tap
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 - hanh tang cua nhung ((cong tap) OR (cuong tap)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (30 trieu)) tinh - hanh tang cua nhung ((cong tap) or (cuong tap)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (30 trieu)) tinh - hanh tang cua nhung ((cong tap) or (cuong tap)) toan cao*.
