Yu Yang did everything possible to save money throughout the production of his short film. As an example, he asked his classmates to draw sketches for him, and he asked his acquaintance, the musician Yike Jia, to compose the film's score.
The short film was in fact never completed.
It only took Yike Jia one week to finish the soundtrack.
The original script was intended to be lengthier, but the workload was so severe that it was abandoned. Another reason the script obstructed was because Yu Yang and Feilong Chen were required to seek their professor's counsel.
