Since the establishment of the "Four New" Party Building Lecture Hall, there have been three frontline case handling prosecutors from the Party Branch of the First Procuratorate Department of Jilin Provincial Procuratorate in the lecture hall, combining their own case handling experience, exchanging and sharing experiences on the integration of party building and business work, and better integrating "from a political perspective" into the entire process and all aspects of procuratorial duty handling, in order to enhance the cohesion and combat effectiveness of the team through party building work. The Party Branch of the First Procuratorial Department of the court relies on the lecture hall to explain the concept of new era procuratorial work through the Party building platform and continuously break through, solidly promoting the integration, promotion, and improvement of Party building and business. In September 2022, the "Four New" Party Building Lecture Hall of the Party Branch of the First Procuratorial Department of the People's Court promoted the transformation of judicial concepts and improved the quality and efficiency of case handling, and was selected as one of the first batch of "Top Ten Cases" for the deep integration of party building and business in national procuratorial organs. Based on the new era, the Jilin Provincial Procuratorate launched a new concept in December 2019. In response to the issue of "low integration of party building and procuratorial work" discovered during the highest inspection, the Jilin Provincial Procuratorate deployed a development platform for deep integration of party building and procuratorial work, and created a "New Era, New Party Building, New Concept, and New Action" party building lecture hall. It called on procuratorial personnel to use party building as a carrier to tell the new concepts and new actions of procuratorial work in the new era, Integrating party building and business work, making party building work in government agencies a source of high-quality development for procuratorial work, stimulating the inherent potential of police officers, and promoting ideological sublimation. In December 2020, Li Fang, the prosecutor of the First Procuratorial Department of the court, stepped onto the podium of the first "Four New" Party Building Lecture Hall. He explained his thinking in handling a second instance appeal case he had handled. After the end of the lecture hall, 18 party members of his first procuratorial department held a big discussion, from writing speeches to sharing on stage and then evaluating at the party member conference. Everyone gained a new understanding of how to do procuratorial work "politically" well. Our Party Branch of the First Prosecutorial Department closely relies on the 'Four New' Party Building Lecture Hall to boost cohesion, strengthen the foundation, and contribute to our positions, solidly promoting the integration, promotion, and improvement of Party building and business. Liu Yanhua, Secretary of the Party Branch of the First Prosecutorial Department, said that since the establishment of the 'Four New' Party Building Lecture Hall, all the police officers of the First Prosecutorial Department have focused on the fundamental principles of procuratorial business, and have been deeply engaged in procuratorial business experts for many years to share their feelings and thoughts in handling procuratorial cases, Through representative cases, describe the changes in judicial concepts in the process of building the rule of law in Jilin. With the continuous improvement of the brand power and influence of the "Four New" Party Building Lecture Hall, the theme of the lecture hall has also expanded from procuratorial business to various fields of procuratorial work. Three years ago, the first procuratorial department of the Jilin Provincial Procuratorate had two business data that were relatively backward. In order to reverse the backward situation, the Party Branch of the First Procuratorate Department has diligently honed its internal skills and selected three people to participate in the "Four New" Party Building Lecture Hall, breaking the bottleneck of business development through the "knocking brick" of Party building. Focusing on the theme of each issue of the Party Building Lecture Hall, the Party Branch of the First Procuratorate Department strives to fundamentally change its concept and improve quality and efficiency, standing in the effective punishment of crimes and strengthening judicial protection of human rights
