The cheer team has made a number of public appearances since 2002, when 300 of them arrived on a ferry at the Asian Games in Busan.
Defectors say they are chosen through extensive background checks and many are members of well-connected families. They are chosen on a strict appearance criteria and analysts say they are less likely to defect. The Mail Online reports these standards are "to be over 1.65 m bar those with exceptionally good looks."
There's also a precedent of motive to not speak about their activities - 21 members of the squad were reportedly sent to a prison camp for speaking about what they saw after a 2005 performance in South Korea.
The Guardian reported that there have been some awkward moments surrounding their orders to perform in cheer:
The North Koreans refused to acknowledge their fellow performers. There were other moments of awkwardness as well. After Team Korea lost and the stadium cleared out, they remained singing to a mostly empty ice rink.
The Korean team was beaten 8-0 by Switzerland in their first match, and 8-0 in their second match to Sweden.
Their final match takes place against Japan on 14 February, however both teams have been eliminated from playoff contention for medals.
