Hong Kong’s Security Bureau has defended its decision to appoint singer Hins Cheung as a mentor in a “rehabilitation project” for youngsters arrested during the 2019 protests, saying it welcomes individuals from all backgrounds to share positive life experiences following criticism from internet users in mainland China.

The project, which has been running for two years, aims to support the rehabilitation of about 7,000 people arrested during the social unrest but not prosecuted.

“[Activities] include invitations by the Security Bureau for interested individuals, regardless of their background or sector, to participate in sharing and exchanges with those young people, so as to share positive life experiences,” a bureau spokesman said.

“These efforts have provided them with an opportunity to turn over a new leaf and start afresh.”

A sharing session featuring Cantopop singer Cheung was scheduled for this Tuesday, his manager confirmed earlier. Some young people arrested during the 2019 unrest have been invited to attend.

The bureau spokesman declined to provide further details of the event. The South China Morning Post also approached the Hong Kong United Youth Association, organiser of the session, for comment.
