1. Parents and children are participants in the interaction, but children must be the main body in quality parent-child interaction. The so-called child-centered interaction means that our parent-child interaction should start from the child's interest and play the activities that the child wants to play in the form that the child likes.

2. Parents should pay attention to children's interests, see their needs and listen to their voices in parent-child interaction. With children in mind and eyes, action will help children's development.

3. In the process of playing with children, parents should not only pay attention to children's language expression, but also look at their emotions, whether they are interested in activities, whether they can concentrate and watch their movements. Children can't fully express themselves through language, and parents need more patience and love to listen to their hearts.
