Since the beginning of the 21st century, China's education and the reform of the construction of the teaching staff have made great achievements, and the number and quality of teachers have been improved. Among them, the key to the development and progress of education is to understand the requirements of teachers' ethics, strengthen the education of "four histories", learn from teachers' moral models, abide by the standards of teachers' ethics, and abide by the bottom line of teachers' ethics. The importance of teacher's ethics education has been shown in many Chinese film and television works. The film presents the "requirements for teacher's ethics", that is, to remember the mission, not forget the original intention, love the post and work, teach and educate people, and strive to cultivate patriotism and cultivate noble teacher's ethics. Whether teachers' ethics can be observed and upheld in teaching work is the primary standard for evaluating the quality of teachers' teams, and is also the focus of teachers' ethics education reflected in Chinese teachers' films since the 21st century. In 2018, Huang Danian, a biopic film directed by Cheng Ke, took Huang Danian, a professor of geophysics and doctoral supervisor of Jilin University, as the prototype, and vividly described Huang Danian's life of being the first in teaching and conscientious in teaching. Adhering to the great ideal of "revitalizing China is our responsibility", Mr. Huang integrated his patriotism and ambition to serve the country into the great cause of building the motherland and into the teaching and scientific research work day after day. Whether it is a British company that asks for a huge amount of liquidated damages and is not allowed to take away a piece of paper, a city manager who acts according to the rules without mercy, or a project colleague who is not willing to accompany when the funds are insufficient, Miss Huang has always adhered to the noble sentiment of indifferent to fame and wealth, willing to contribute, coping with the difficulties in scientific research and teaching, starting from his own work, and demanding himself with noble sentiments and moral standards, With a firm attitude, we have cultivated a number of outstanding students and academic leaders in education. The film's presentation of "strong 'four history' education", strong "four history" education, in the teacher's ethics education, encourages many teachers to draw nutrients from the profound historical culture, obtain spiritual strength, lead the teaching team to devote themselves to the great goal of teaching and educating people, and to the great struggle to achieve the "two hundred years". The "four histories" include the history of the Communist Party of China, the history of new China, the history of reform and opening up, and the history of socialist development. In the learning of the "Four Histories" education, teachers constantly improve their theoretical level and political literacy, and guide students to learn the "Four Histories", so that the builders of the motherland can contribute wisdom and strength to the Chinese Dream of the great rejuvenation of the Chinese nation in the future. The documentary "Zhang Guimei: Seeing a Larger World", which was launched in 2020, tells about Zhang Guimei, who won the honorary title of "National Model of Teachers' Ethics", working with a firm party spirit and dedication. When material conditions were extremely scarce and many teachers and staff questioned whether Huaping Women's High School could continue to run schools, and when there were only six Party members and eight teachers in the school, Zhang Guimei, adhering to the simple belief that "as long as there are Party members, there is nothing impossible", led five Party members and teachers to review the oath of joining the Party together, and personally drew a party flag on the wall on the second floor of the school, and wrote his own oath of joining the Party one by one, In this way, we can encourage ourselves to remember our original intention and mission.
