Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
thong cong » trong cong, tong cong, thong thong
thanh toan » thanh hoa, thanh san, tinh toan
hanh dung » thanh dung, anh dung, hanh dong
dung cong » dung trong
ho chieu » hoc thieu, doi chieu, mot chieu
dung cua » dung luan, dung cho
toan tap » toan 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: ((theo chieu) OR (ho chieu)) sang - hanh dung cua ((dung cong) OR (thong cong)) thanh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (ho chieu)) sang - hanh dung cua ((dung cong) or (thong cong)) thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (ho chieu)) sang - hanh dung cua ((dung cong) or (thong cong)) thanh toan tap*.
