College students are in a special period of physiological and psychological development and maturity. With the increasing pressure of learning and life, parent-child conflicts often occur, and poor communication can make parent-child conflicts more serious. Painting therapy uses painting as a medium to communicate with the individual's subconscious, thereby improving emotional disorders and repairing parent-child relationships. This study takes a female college student as an example. Through painting therapy, she learns self relaxation methods, assists her in mastering mandala painting therapy for self-awareness, alleviates parent-child conflicts, improves parent-child relationships, promotes reasonable self-awareness and self-acceptance, and promotes individual mental health and development. At the same time, exploring individual interventions in parent-child conflicts can also enrich research on painting therapy.

This paper aims to explore the use of "Internet+" technology to flip the traditional classroom teaching model in order to better enhance students’learning outcomes in the fields of medical microbiology and immunology. Through research and practice, it has been found that the flipped classroom approach can stimulate students’ interest in learning, enhance their ability for self-directed learning, and promote deep learning. This paper will combine specific cases with the latest research findings to propose more concrete teaching strategies and suggestions, and discuss how to effectively evaluate the application effects of the flipped classroom in the teaching of medical microbiology and immunology. The goal is to provide reference and inspiration for educational reform.
