His comments came as the school's Communication Society was admonished for publishing "The Third Anniversary of Siege of the Hong Kong Polytechnic University" on social media and were asked to suspend operations on Wednesday.

Wai said the society would hold an election soon, with the punishment levied this time only over the post and not affecting its operations next term.

The since-deleted post was published on the society's Facebook page on November 18, referring to the memorial of the "third anniversary" of the siege at PolyU.

The post was considered "inappropriate" and has led to the society being banned until February 28.

It is not allowed to use any of the school space or the facilities, including its office, and email.

Wai said yesterday that the PolyU incident involved violence and illegal behavior, with some participants being convicted, and that the post was misleading.

He added that the incident can be discussed among students, however, it depends on how it is discussed.

"We oppose any acts that may involve exaggerations or misleading statements," Wai said.

Some students might have concerns regarding their actions during the 2019 unrest, and that the campus should be a place of learning, he added.

The university will support the rehabilitation of students and arrange for some students who were released from prison to be readmitted.

The society was scheduled to hold a letter collection event for inmates in mid-November "to provide comfort to those who are imprisoned." However, it was canceled because it provoked complaints and the university rejected its application for a venue to stage the event.

Additionally, the university stopped collecting membership fees on behalf of the student union from the current academic year.
