The One Who Runs Away is The Ghost testifies to the infinite potential of the documentary genre. After spending her childhood at the center of electronics production in Shenzhen, China, director Qinyuan Lei developed a magical format of presenting personal memories. To recall her own experience, Lei follows the two sisters Haohao and Zhouzhou (five and eight) as they wander through Shenzhen's electronics center. Although she has no relationship with them, the daily life of the sisters is described as if they were her memories. Lei's camera finds scenes that show how children's minds work, separated from the adult world, capturing with astonishing closeness as they play their breath-holding game, as they roam the spooky halls, and as they are buried in the rubble of electrical gadgets. She adds narration to children's adventures, allowing the audience to discover the ghosts of childhood and peek into the world they live in at the same time. The children's sensibility to use a shabby environment as a playground, and their imagination to transform the small everyday world into a mysterious and vast universe make this documentary an interesting and unforgettable experience.​
