According to Professor Shi Changjie, the reason for production with both 2D and 3D software is to preserve the original illusory world of Jimmy and to create multiple yet realistic impressions of space."A Fish With a Smile " achieves this feat through production despite the incredibility of the outside world, and really constructed from the two-dimensional world as depicted on flat surface a three-dimensional world of strangeness and wonder. 3D director Duan Yilun has said that ordinarily, 3D hardware is used mainly to express special 3D spaces or different angles in film, but in accordance with the light colors of Jimmy's original works and in search of a realistic space that can arise from the pages of the story, the sculpting of the set, light direction and camerawork have all transformed into high difficulty, high skilled manipulations.
