Perhaps you should try some spelling variations:
luan tuong » luan luong, luat thuong, xuan truong
theo chieu » ho chieu, theo chu, thi chieu
tuong cong » truong cong, trong cong, tong cong
hanh dung » thanh dung, anh dung, hanh dong
dan toan » van toan, dan than, manh toan
dan chan » dan gian, dan ca, van chat

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 (theo tieu)) sang - hanh dung luan tuong cong ((dan toan) OR (dan chan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) sang - hanh dung luan tuong cong ((dan toan) or (dan chan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) sang - hanh dung luan tuong cong ((dan toan) or (dan chan)) tap*.
