What is the identity of serving the people on the chest?

During the Cultural Revolution, there was a badge with the words "serving the people" written by Chairman Mao. Dear Premier Zhou always wears it on his chest. Premier Zhou is a model for serving the people and our good premier! As soon as some units enter the door, they still hang the words "serve the people", which shows that the party and the government take serving the people as their purpose and always remind us not to forget to serve the people and not deviate from their purpose. The identity of the representative who serves the people on his chest is that only by truly serving the people can he be qualified to wear this chapter and be a real party member-level person. People who consider their own interests everywhere do not deserve to wear the badge of serving the people, because they are not qualified! This is identity. (Ming Fan Huifu)
