The work titled "Sign" consists of two parts.? Part 1 is disguised as an educational video with two instructors teaching basic sign language for mothers to communicate with their children.?? One of the instructors in Part 1 appears to be an Australian native (with Pacificean features), and the other is a blonde-haired westerner.? While the former teacher explains the lesson using signs, the latter just stands and smiles, and the subtitles explain the content of the lesson.? This footage suggests that typical lessons from television programs often leave viewers with a certain awkward feeling. In Part 2, a mother is teaching her baby using baby sign language in the peaceful scenery of Australia.? The loving expressions of the mother and her innocent child are contrasted with the words that the mother teaches with baby sign, hinting at a merciless aspect of the real world.
