The party committee of our group held a party day event with the theme of commemorating heroes in the Qingming Festival. More than 120 representatives of party members and cadres were organized to visit the Pingjin Battle Memorial Hall to deeply cherish the great achievements of the older generation of proletarian revolutionaries. In the Pingjin Battle Memorial Hall, everyone listened carefully to the commentator's introduction, understood the historical details, and deeply understood the original aspiration and mission of the Chinese Communists, and then carried out the activity of reviewing the oath of joining the party.
