The construction of teachers' morality and style is an eternal task in the construction of teachers' team, which is related to whether the school can adhere to the fundamental task of cultivating morality and talents, and whether it can cultivate qualified builders and successors of socialism with Chinese characteristics. However, at present, there are still some problems in the construction of teachers' morality and style, such as teachers' misconduct, academic misconduct and so on. To strengthen the construction of teachers' morality and style, we should not only strengthen teachers' self-discipline, but also strengthen external constraints through sound assessment, supervision and punishment mechanisms.
