Early in the morning, walking along the promenade, I met the children who came to us and said good morning with smiles on their faces. The sound of good morning breaks the silence of the morning and starts the beginning of the day. Saying good morning is one of Renhe's etiquette campaigns, and the children have gradually gotten used to it. However, they are very skillful at reading people, and the children will not interact with each other if they are not taught by example. The principal reminded them that it is important to behave themselves no matter what. Towards the end of the semester, apart from physical fitness tests, the children will also have a chance to have their physical fitness tested.
