The captain of SNH48's 1st team rendering a pretty old English song & then showing off her dancing skills w/ a teammate at a theater performance of the team specially held a couple of days ago for celebrating her birthday:
Both she & that teammate are former BEJ48 members, tho they're originally SNH48 members before transferring to BEJ48 back then.
[EDIT]
While all the heavyweights of BEJ48 have now been transferred back to SNH48, BEJ48 is still alive & kicking - a couple of promotion videos for their current prominent members:
^ The captain (of the entire group - all their former three teams have been abolished due to insufficient number of members after the mass transferal of members to SNH48 & withdrawal of other members back then).
^ A popular, towering member.
