Training can be based on the characteristics and needs of party activists and development targets, carefully set up party classes such as "recalling the century-old party history to build a loyal police spirit", "learning the party history, remembering the initial heart and taking on the mission", and organize to watch documentaries such as "Letter from Hongyan", "At the beginning of the great rejuvenation" and "Kerr taking bribes", so that students can learn the strength of unremitting struggle from the century-old party history, fully feel the charm of party classes, and have firm confidence and determination to follow the party.
