College students should make full use of the talent resources in the school and absorb knowledge and methods from various channels. If you meet a good teacher, you can take the initiative to ask them for advice, or ask them to recommend some extracurricular reference reading. In addition to senior professors, young teachers, doctoral students, master's students and even their own classmates are the best sources of knowledge and learning partners. Everyone has different understanding and understanding of problems. Only by helping each other and learning from each other can we make progress together.
