On the afternoon of September 2, Suzhou High School, Nanjing University of Aeronautics and Astronautics (China) posted a recruitment notice for janitors as follows:

By the evening of September 14, the school officially announced the recruitment of contract staff for the position of janitor. Specifically as follows:

"Based on the Recruitment Guidelines for Contract Employees in the Suzhou Industrial Park Education System , after going through the steps of recruitment announcement, application review, internal interview, council evaluation and school party committee approval, Mr. Li Yongkang was officially recruited:

Job position : Janitor

Full name : Ly Vinh Khang

Gender : Male

Date of birth : March 2000

Education : Master (postgraduate)

Information announcement period: From September 14 to September 25. During the announcement period, if there are any problems, please contact the school principal.

Immediately after posting a recruitment notice for a janitor with a master’s degree in Physics, Suzhou High School received a lot of criticism. Many people said that this was a waste of resources and unnecessary. Others said that the unemployment rate of young people in China is increasing, and it is normal for highly qualified people to do manual labor.

In response to the controversy surrounding this announcement, on the evening of September 21, the school's party committee representative - Mr. Vuong Kiem said that there was confusion about the candidate's educational qualifications.

"During the drafting process, the school staff made a mistake. Ly Vinh Khang has just graduated with a bachelor's degree and has not yet completed his master's degree. We will learn from our experience and soon issue a new announcement," said Mr. Kiem.

I would like to express my heartfelt gratitude for the 'consideration' of Can Tho University for me, an elderly student who was lucky enough to pass the exam... - Mr. Nguyen Tan Thanh, 87 years old, a new graduate student shared at the opening ceremony of Can Tho University's postgraduate program.
