     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.

     "It is right for young graduates to be ambitious (有抱负的). But they have to start in a solid and down-to-

earth way," Cai said. Cai is not alone in making such a choice. The company has got 12 college students in all.

     "I come for the 800 yuan monthly pay," said Xiao Ji, who is a student from Nanjing University. "I have

grown up and no longer live on my parents," he said.

     "Working as shoe shiners can mean a bright future," Cai said.

     Not everyone can accept this job choice. Cai's girlfriend left him because she felt ashamed to be with a

shoe shiner, and Cai accepted the fact. "This is the price to be paid for a job," he said.

     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.
