Can helping clean campus cultivate self-discipline?

A university in Qingdao, Shandong province, has replaced some of its cleaning staff with students, saying this could "help cultivate an awareness of self-discipline and service among students".

Students at Qingdao University of Technology have been tasked with cleaning the school twice a week in groups of four or six. Their performance is being graded, and whichever of the university's eight colleges receives the highest grade is awarded 10,000 yuan ($1,440) each month.

However, some students are not happy about the practice, especially with final exams approaching.
