Compared with Beijing, Shanghai and other big cities, these cities have a relatively low Cost of living, a relatively stable and comfortable life, and many development opportunities and large space, which can also better realize personal value. College students believe that although there are many opportunities in first tier cities, human resources are also relatively concentrated and competition is fierce. The personal development prospects are not clear. Especially with the further expansion of urbanization towards second and third tier cities, these cities have shown enormous potential in terms of economic development speed, wage levels, and personal development space.

In fact, since 2004, China's second and third tier cities have gradually shown a strong "magnet effect" in the job market with their good development prospects, work environment, and living conditions, attracting college graduates and senior talents. With the development of society and the improvement of the overall level of public services, second and third tier cities will become new destinations and spaces for many college graduates to find employment, and can also become new spatial carriers to alleviate the employment pressure of the population in large cities.

In recent years, with the rapid rise of housing prices in first tier cities, the increase in job competitiveness, and the relatively low treatment, second and third tier cities have gradually shown a strong "magnet effect" in the job market with their good development prospects, relatively elegant and comfortable working environment, and relatively relaxed living conditions, attracting college graduates and senior talents. Experts say that returning college students to second and third tier cities for job hunting and employment is not only a rational return, but also an inevitable trend of social development. For second and third tier cities, it is crucial to seize the opportunity of rational talent flow. Therefore, it is necessary to accelerate the formulation of talent strategies, attract and retain talents, cultivate talents, and fundamentally enhance the sustainable development ability of cities
