Douyin is essentially a music short video community focusing on young people. Users can choose songs and match them with short videos to form their own works. It is similar to Xiaokaxiu, but the difference is that Douyin users can make videos more creative through video shooting speed, video editing, special effects (repeated, flash, slow motion) and other technologies, rather than simply lip syncing.
