The challenge of management originates from the continuously growing the management system’s complexity, whose essence lies in the interaction of the connections with the differences among the system’s elements. These interactions create powerful information Shi,thus showing the uncertainty that is caused by the phase change and forks. Therefore，the effective strategy dealing with the complexity is to obtain more amount of the information by abstraction to built a lot of information Shi.The core of Shi science’s principles is the principle of symmetry.The operation mechanism of Shi science is that the differences promote the connections, the connection enlarges the differences，and move in a circle. From the asymmetry to the symmetry and from the symmetry to the asymmetry again, displacement groups shift to alternate groups to arrive at alternate groups with higher level in this reciprocal process. So,the social evolution and developments are promoted spirally to transform the harmony in management into the harmony in the society.
