With the development of the new situation, the "00s" have become the mainstream college students in universities, and the "05s" are about to enter universities. The group of college students born in the 2000s has shown ideological characteristics such as high openness, strong self-esteem, strong individualism, active thinking, and weak psychological resilience, which have brought new challenges to ideological and mental health education in universities. At present, it has become a common trend for graduate students in universities to serve as part-time counselors, and the structure of university counselors is generally "a combination of full-time and part-time, with full-time as the main focus, and full-time leading and part-time". As a full-time counselor in a university, I have worked as a part-time counselor during my graduate studies. Based on my personal and practical experience as a part-time counselor, I will consider and study the impact of part-time counselors on the construction of the university counselor team. In order to make the construction of the university counselor team more professional, professional, and diversified, I will propose constructive suggestions.
