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

- Basic requirements: Good ethics, stable health, law-abiding, responsible, honest, hard-working, diligent, willing to follow school arrangements and have communication skills.
- Gender and age: Male, under 50 years old.

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

Job position : Janitor

Full name : Ly Vinh Khang

Gender : Male

Date of birth : March 2000

Education level : Master (postgraduate)

Major : Physics

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

Immediately after posting a notice to recruit 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 Chinese people is increasing, and it is normal for highly qualified people to do manual work.

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

"During the drafting process, the school staff made a mistake. Ly Vinh Khang 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," Mr. Kiem said.

I would like to express my heartfelt gratitude for the 'care' of Can Tho University towards 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.
