The modernization of preschool education, as an integral part of the modernization of Chinese education, highlights the characteristics of popularization, universal benefit, high quality, and the modernization of children, and "the modernization of teachers" is its important force. Preschool education in Guangdong has been striving for ten years, and its popularity has been continuously expanded, inclusive resources have gradually increased, and the quality of conservation education has been steadily improved. In the face of the new beginning of promoting the overall strategy of Chinese-style modernization, through the analysis of the current situation of the construction of preschool education teachers in Guangdong, three challenges are identified: firstly, the serious imbalance in the structure of the teacher team at the source; secondly, the inadequate ability of post-specialization continuous supply in the quality matching level of the teacher team; and thirdly, the lack of correspondence in the construction emphasis, especially in the context of educational digital transformation. Facing the future, the reform of the education supply side will become the top priority in the construction of preschool education teacher team in our province. The preschool education in Guangdong needs to break the problem through three "strengthening teachers" approaches, that is, to adjust and optimize the structure of the talent team from the source through in-depth development of pre-service and post-service multiple paths, so as to enhance the quality of teaching and research and enhance the sustainable supply of post-service majors, and to improve the digital literacy of teachers to empower the digital reform of preschool education.
