Info by Transition @ Selina's AF:
Selina is slowly getting back to work as she recently did charity for people with disabilities. She hopes that S.H.E will be able to reunite at the end of this year and disclosed that they have already started to collect songs.
During the time when she was injured she did consider not doing this (entertainment work) any-more but as time went by and she got better faster than expected she had other thoughts.
If she really likes to sing and perform she shouldn't restrict herself. When she has gotten better she can still sing and have concerts with her sisters.
As for people spotting her scars on her arms at her wedding she said that those scars are actually the smallest ones on her body.
