Since the 18th National Congress of the Communist Party of China，the Party Central Committee with Comrade Xi Jinping at the core has revolutionized the party’s inspection system，creatively proposed the concept of “political inspection”，and in practice developed political inspections into the strategic institutional arrangements for supervision and an important institutional form of political supervision. According to the practical process of comprehensive political inspection，its fundamental experience and institutional achievements are to promote the idea of “political supervision” under the guidance of Xi Jinping’s thought into practice，and to form a practical system of inspection and supervision which covers the inspection of political beliefs，political leadership，political capabilities and political ecology. Political inspections are not only conducive to our party’s discovery and correction of political deviations and strengthening the implementation of political responsibilities，but also with its unique institutional advantages，it has a special position and an important role in the political system of the Party and the country.
