The application of positive psychology in the work of mental health education in colleges and universities can help students better face setbacks, enable students to face learning and life with a positive attitude, and promote students' future development and promote students' healthy growth. Based on positive psychology, this paper analyzes and discusses its practice and exploration in college students' mental health education.

Taking Guizhou University of Commerce as an example, the author pointed out the problems in current Japanese language teaching in universities and proposed improvement measures from three aspects, aiming to explore a suitable path for Japanese language teaching in commerce colleges.

Since the reform and opening up, China has continuously pushed forward the administrative system reform, adapted to the national conditions and the requirements of the times, and achieved fruitful results. Generally speaking, the successive administrative system reforms have focused on the government and the adjustment of the dynamic relationship between government-market-society. Due to the special characteristics of local foreign affairs departments in the administrative system, the successive reforms have provided less guidance to them, and related research is also relatively lacking. However, from a practical point of view, local foreign affairs offices have long followed the pace of administrative system reform and carried out a series of adjustments and optimizations. As an important element of administrative system reform, the functional transformation of local foreign affairs offices has been continuously promoted along with institutional reform. This research, which is mainly based on talks and supplemented by document comparisons, aims to study the development results and experiences of the Foreign Affairs Office of Shaanxi Province in the context of administrative system reform, and tries to provide a case study for the administrative system reform of local foreign affairs departments.

In this study, the authors propose a method that combines CNN and LSTM networks to recognize facial expressions. To handle illumination changes and preserve edge information in the image, the method uses two different preprocessing techniques. The preprocessed image is then fed into two independent CNN layers for feature extraction. The extracted features are then fused with an LSTM layer to capture the temporal dynamics of facial expressions. To evaluate the method's performance, the authors use the FER2013 dataset, which contains over 35,000 facial images with seven different expressions. To ensure a balanced distribution of the expressions in the training and testing sets, a mixing matrix is generated. The models in FER on the FER2013 dataset with an accuracy of 73.72%. The use of Focal loss, a variant of cross-entropy loss, improves the model's performance, especially in handling class imbalance. Overall, the proposed method demonstrates strong generalization ability and robustness to variations in illumination and facial expressions. It has the potential to be applied in various real-world applications such as emotion recognition in virtual assistants, driver monitoring systems, and mental health diagnosis.

Tennis, as an important project of sports, has an obvious role in cultivating students' physical quality, observation ability and reaction speed. Under the background that the country attaches great importance to students' physical literacy, the traditional single and passive teaching has been unable to meet the practical needs, so it is necessary to strengthen the innovation of teaching methods. With the recognition of many teachers, the teaching method of "combining competition and practice" has been continuously promoted. The paper takes the combination of competition and practice as the teaching mode, and studies the teaching of college tennis sports.

As a masterpiece of ancient mythological stories, The Mirror's Fate contains rich and complex religious connotations, but the study of the religious and cultural thoughts of The Mirror's Fate is still thin. This paper intends to start from the aspect of Taoist cultural thought, through the analysis of Li Ruzhen's theory of creative mind, to discuss the theme of Mirror Flower Fate, the plot structure of the novel as well as the novel's characters, in order to deepen the understanding of the cultural meaning of the novel.
