Inspection is an important responsibility entrusted by the party constitution and is a strategic institutional arrangement of inner-party supervision. Since the 18th National Congress of the Communist Party of China，the inspection has made great innovative achievements in theory，practice and system，effectively solved the long-standing problems of inner-party supervision，basically formed an effective linkage inspection pattern，significantly strengthened the sense of awe of law and discipline among party members and cadres，promoted the improvement and reform of system implementation，and promoted the obvious improvement of Inner-party political ecology. The inspection has become a bright “business card” of inner-party supervision；At the same time，we have accumulated valuable experience such as actively and openly breaking the mystery，consciously implementing the decisions and arrangements of the Party Central Committee，always adhering to the people’s position，paying attention to the grass-roots foundation and practical experience，which provide new nutrients for the innovation and development of patrol inspection.
