A firm proverb ... in primary schools, this belongs to the category of class management, and the leading power and execution power belong to the class tutor; The final audit of junior high school is the class tutor, and the content and implementation are usually left to the students themselves; This has evolved from class management to a part of high school students' class autonomy. As long as it does not violate public order and good customs, schools and class tutors generally do not interfere.
So primary school teachers look at their class management attitude. Some teachers are very serious and may change every week. Some teachers don't attach importance to school motto. They stick to several idioms from the beginning of school to the end of the year. Of course, there are also some schools that have upgraded their motto to the level of character education from top to bottom. Many schools adopt Tzu Chi's meditation language, and not only stick it on the wall, but hold activities related to meditation language (comics/calligraphy/storytelling/painting ...) throughout the year.
Because of the high pressure of entering a higher school in senior high school, schools/teachers/students don't pay much attention to this kind of thing, and there are many words like proverbs in Chinese textbooks, so school announcements and class announcements are often posted in the classroom.
