Theory derives from practice，and develops and gets enriched in the process of guiding practice. Practice is the source of the theoretical innovation，and drives the theory to develop. Secondly，the aggressiveness of practice and the expansibility of theory build upon each other in the dialectical development of socialism with Chinese characteristics. In conclusion，constant enrichment and development of the theoretical and practical features of socialism with Chinese characteristics are the inherent requirements for building and developing the socialism with Chinese characteristics.
