As the most basic unit of education and teaching, there are many seemingly unremarkable events and news every day, which constitute the elements of students' life and the life breath of education and teaching. Things are happening and days are flowing. Emotional roughness and indifference have also become blind spots that we rationally ignore. Many of our educational ideas on paper have also widened and deepened the generation gap between teachers and students, and even become a greasy black floating object, which hinders us from seeing through the clear spiritual world of students. The most difficult thing to explore in the world is the profound and unpredictable spiritual world. Sometimes, our self-righteous and self-satisfied educational evaluation is actually a blind man touching an elephant or a blind man riding a blind horse. The educational gas field is by no means a regular whole with simple components and single elements, but a complex and changeable gas field turbulence composed of many independent gas fields. A person is an aura, a dormitory, a class and a department are all aura. They are intertwined and collide with each other, forming a colorful educational climate and a vibrant educational ecology. We ask students to write class diaries and weekly diaries, and we deeply feel what a colorful little universe the students' life world is. Many times, we often only look at its appearance with colored glasses, and often make empirical common judgments because we are limited by the usual mindset. In fact, all judgments are flawed and arbitrary, and the extraction of commonness is often based on the consistency of personality. The essence of education is awakening, awakening students' self-cognition, self-correction and self-correction; Stimulate students' passion for self-discovery and self-transcendence, which is what we call educational wisdom beyond knowledge and ability; It exudes the courage and enthusiasm of students who love life and devote themselves to life. Life is dull, not only because of the similarity of life content and the singleness of life form, but also because of our insufficient investment and incorrect attitude. A philosopher said to the owner of the garden, "Although this garden is yours, I have seen much more than you." This is the confidence covered and penetrated by the light of cultural spirit, and this is also the confidence that wisdom overlooks and examines. Through the writing of class diaries and weekly diaries, many students have learned to observe and feel life, and found that there are waves and turbulence, fun and bright colors in ordinary life. The charm of youth lies in the depth of one's exploration of life. Especially in this impetuous and noisy era, universities have lost their former calmness and tranquility. Educational anxiety is a common symptom in current society, which reflects the existential anxiety prevailing in China. Capitalization and administration of education have dismembered education and stirred people's hearts like boiling water. Writing class diaries and class weekly diaries is to let our overly vague eyes slowly shift to the university scenery that we should have and enjoy, and there are also scenery in familiar places. What's more, many college students have graduated from college, and they have no idea what they should get or give up from the university they have been to, because they haven't learned about the university and haven't learned to see the world from the perspective of the university. Come in a hurry and leave in a hurry. In fact, the university is still strange to most people. The beauty of youth also lies in the performance of our youth. College life is the most colorful part in the picture of youth, and the quality of college life directly determines the quality of life. Memory is a brush that fixes the color of youth and a yeast that brews youthful wine. The value of a university lies in the retention and solidification of memories day and night. Personalized memory preservation will always enrich the connotation of the university and write the longest and mellow story of the university. Although these class records and weekly diaries will turn yellow over time, they will become the genes of university culture and be passed down from generation to generation. The university is so big that it is getting stronger and stronger. In this way, the history of the university has become thick and broad by different people, different pen and ink and different memories. This is our ideal, but when the whole education turns to power and money, idealism is a noble with lofty spirit. Our colorful and lush diaries and weekly diaries have become our slightly tragic resistance to the world wind!
