While guiding students to communicate, I also pay special attention to reminding students what to do. Through my kind reminder and communication with my classmates, I let the children know what they should do and how to do it. On this basis, I also ask students to reflect on their recent behavior, what they have done and what they have done badly. Many students have exposed their own shortcomings. Some students say that they don't get along well with other students at ordinary times, and sometimes they swear if they don't pay attention. I was very happy to listen to the children's speeches, because the children not only learned knowledge in the etiquette class, but also realized their own shortcomings. This is killing two birds with one stone.
