Few students would dream of getting a job as a shoe shiner working along the street. College students, in their own eyes and in the eyes of the public, are expected to get at least a proper job, if not working in a high-income or white-collar position.

Cai Yong’s decision to work as a shoe shiner shocked not only his parents, who had high hopes for him, but also his girlfriend.

12 college students in all.

A former shoe shiner, Zhong Haibo, from a medical college, believes it was a good training for the rest of his life. “There is nothing I can’t do after working as a shoe shiner,” Zhong said, meaning that such kind of experience in early life is helpful in a future job.
