The number of college graduates in 2022 is expected to be 10.76 million, an increase of 1.67 million year-on-year. This is the first time that the number of college graduates has exceeded 10 million, and it is also the year with the largest growth in recent years. The employment pressure of 10.76 million college students, coupled with the arrival of the post-epidemic era, makes the employment of college students face a grim situation again. Improving college students' employability is an important measure to cultivate college students' positive employment psychology and solve college students' employment problems. It is the choice of many colleges and universities to improve students' employment ability through out-of-school practice teaching bases. Practice teaching bases can benefit students, colleges and enterprises, promote social harmonious development and realize the strategic goal of rejuvenating the country through science and education. It is of great significance to the development of society and individuals.
