Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh luan » trinh luan, trinh luat, doanh luan
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
cua tinh » cua sinh, va tinh, hoa tinh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban
ha tinh » va tinh, may tinh

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 ((ha tinh) OR (cua tinh)) - hanh tranh luan ((nhung cong) OR (thong cong)) tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((ha tinh) or (cua tinh)) - hanh tranh luan ((nhung cong) OR (thong cong)) tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((ha tinh) or (cua tinh)) - hanh tranh luan ((nhung cong) OR (thong cong)) tan toan tap*.
