So long, So Ching: girlfriend of Hong Kong dancer injured in Mirror concert accident quits girl group Collar, cites trauma
- In Instagram post, 27-year-old says she is still haunted by scenes of trips to the hospital and emergency ward
- Management company MakerVille, which also oversees boy band Mirror, confirms departure and says it will continue to support group

So Tsz-ching, 27, a member of girl group Collar, on Wednesday announced her exit on social media, revealing the injury suffered by Mo Li Kai-yin after he was crushed by a falling screen had caused trauma that “could not be healed”.
“The scenes of each trip to the accidents and emergency ward and the hospital have been etched into my heart, leaving indelible scars,” So, also known by her stage name So Ching, wrote on Instagram.
“Even though there were moments when I faced everyone and went on stage, I have not been able to fully adjust to on-screen work at the moment.
“After much consideration and discussion with the company, I have decided to leave Collar.”

So’s management company MakerVille confirmed her departure, saying it would respect her wishes and make suitable arrangements. MakerVille also manages boy band Mirror, whose concert last July was marred by the accident involving Li, also 27.
