Looking at the teachers' calligraphy, every stroke is full of tenderness, and every word is full of affection. They use their own calligraphy to express their inner feelings.
Everywhere, we are reminded that we should always have awe and self-discipline, always sound the alarm bell, beware of delays, keep the discipline of honesty and morality ahead, keep the bottom line, do not step on the red line, do not touch the high-voltage line, and keep the "master switch" of good life clean, honest and noble at all times.
