Her job as a university professor was to teach and mentor her students. 

Zheng Feng, an associate professor at Beijing University of Posts and Telecommunications, not only did not do that, but she degraded and exploited them instead.

She was accused of abusing her power by 15 of her students in a 23-page open letter that was shared online on April 9, South China Morning Post (SCMP) reported. She has since been suspended from teaching and tutoring.

In the detailed expose, Zheng, who was teaching wireless communication and digital signal processing technology, is alleged to have made her masters students run errands for her such as buying breakfast, picking up deliveries as well as driving her friends and family.

She also got them to clean her flat and help her daughter with her homework.

Students were even forced to take exams for Zheng's daughter and participate in competitions on her behalf, local media reported. 

They revealed that the professor also made them work in the laboratory for more than 10 hours a day, including on holidays, and expected them to attend meetings after 10pm every night.
