This study explored the professional development issues, challenges, and opportunities faced by calligraphy teachers in the context of disciplinary integration. Descriptive survey was used in the study to explore the professional development of Calligraphy teachers' discipline integration. Through questionnaire surveys and comprehensive analysis, it was found that calligraphy teachers generally believe that subject integration has a positive effect on improving teaching effectiveness and promoting comprehensive development of students. However, in actual teaching, they face the challenge of increased workload and difficulty in integration brought about by literacy in interdisciplinary teaching. In response to these challenges, calligraphy teachers have expressed an urgent need for professional development, especially in organizing classroom teaching and creating various book styles. This study suggests that schools should develop specific training and support plans to meet the professional development needs of calligraphy teachers; and apply the research results to educational practice, providing theoretical support and practical guidance for the innovation and development of calligraphy education.
