Smart primary and secondary school apps have also been optimized in terms of home-school collaboration functions. The members of the class home-school group are all teachers and parents in the class, and teachers and parents can interact in the group. You can also post a notice on the class notice page. Parents can also click on the child's class in my module to view the information of the class teacher, students and parents, or click on a user's avatar to apply for adding friends for communication.
