Abstract: Self-conscious and powerful self-revolution is the "secret key" for the Communist Party of China to be in power for a long time,and inner-Party supervision has provided a reliable way for this.Looking atthe inner-Party supervision from the perspective of the Party's hundred-year history of struggle,its evolution is full of the original mission and footprints of the Party in saving the country,building the country and governing the country.After a hundred years,inner-Party supervision has gradually achieved systematic and strategic development,contributing to standardizing and guiding the use of "public power" by leading cadres.In the future,inner-Party supervision should adhere to the performance goal of inner-Party governance to lead the country's governance,enlightened by historical experience and based on realistic demands.There is an urgent need to continuously improve the efficiency of supervision in accordance with the direction of "full coverage","rule of law","coordination" and "technicalization",and to provide support and guarantee for the modernization of national governance by deeply promoting the strategy of administering the Party in a strict and all-round way.

Key words: Communist Party of China, inner-Party supervision, strict administration of the Party, national governance
