Xiaodong is very concerned about the class group. A slogan or declaration can be written after the colon. According to the relevant information, for example, I care about the collective, have strong self-care ability, and can finish all my homework on time, but sometimes I don't concentrate enough in class and have some small moves. I hope you can stand up bravely and fight against fun and fear of difficulties. Show the purpose and goal of the class, or write down the slogan or slogan of the class to stimulate the cohesion and centripetal force of the class. In addition, the motto or creed of the class can be written after the class colon to express the spiritual pursuit and values of the class.
