Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types.

We first went to the village committee and obtained the consent of the leaders of the village committee. With their assistance, we arranged a row of tables and stools in the courtyard. Two sphygmomanometers were placed on the table, flyers were posted on the wall, banners were hung and flags were erected. Teacher Zhao informed the villagers to come to the village committee on the radio. After everything was ready, we waited for the villagers to arrive with leaflets, brochures and questionnaires. After the announcement was broadcast, villagers came soon. The students greeted them with smiles, handed out knowledge books to the villagers, explained scientific knowledge to the villagers, and conducted a questionnaire survey. Since most of the villagers could not read, we all asked them one question at a time. It may be easy to do one survey, but it takes great patience to do many. In addition, the villagers generally speak local dialect, and some students have some obstacles in communication, but we have all overcome various difficulties. Some of the students are handing out leaflets, some are answering villagers' questions, some are doing investigations, and some are measuring blood pressure for villagers. The teachers are even more integrated with everyone, and they can no longer tell who is the student and who is the teacher. Gradually, the number of villagers increased, and everyone was even more busy. Look at this lively scene: there are investigations, leaflets, interviews, blood pressure measurements and photos-everyone is really busy! In this way, we successfully completed the task of the first stop.
