Having now watched episode 1 & most of episode 2 of #StreetDanceOfChina season 6, I think I can guess what this season's twist is.
So far, we've seen only 3 captains, & the number of towels they've each been given is significantly fewer than previous seasons.
We also know that some veterans of previous seasons have been invited back, but we haven't seen them in the first 2 episodes...
