Chang gai duan is industry shorthand for adapting a long-form drama, or its story property, into a vertical micro-drama of a few minutes per episode, released on apps such as Douyin or Hongguo. The spin-off is cheap to make and keeps a hit's characters and brand in front of viewers between seasons. The reverse traffic, short dramas and their actors moving into long series, has its own names. A commentary on the micro-drama market listed chang gai duan as the typical first move of the long-form studios.

Short to long: China's micro-dramas start sending hits and stars upstream

What the long platforms are buying, what the actors have to relearn, and why a hashtag about short dramas making people stupid makes the move matter.
