but it's also an MNet's editing and media-play
the best ones from China will perform in the next episode
probably this is why they also shown us so many camera close ups with girls from different countries talking about how kgroup is best etc.
then was that moment with Hikaru when many of them said this isn't what they've expected to see from Japanese girl
so they for sure saved things like this for opening of ep.2 as well
if I counted well they showed 29 girls from C group so only 4 of the remain. Two of them are Su Ruiqi and Xu Ziyin.
For j group 19 and K group only 12 (yujin not included)
