1. Principle of good faith. It is beneficial for preschool children to integrate into the group, cultivate their collective consciousness and improve their interpersonal skills.

2. Objective principle. Purposeful participation, such as patriotic education activities, labor education activities, or artistic activities, should have clear goals on what skills or qualities children should cultivate and what effects they should achieve.

3. The principle of pertinence. According to the actual situation of children, what problems exist in children and what aspects should be cultivated and exercised.

4. Activity selection. There must be activities in choosing content, because children are still young, and only by playing in activities and learning in activities can the ultimate educational goal be achieved.
