'Light Chaser' retells household Nezha myth

Over 1,300 days, nearly 1,000 artists have worked on animating 162 roles, with each taking around 360 days to finish. When the workload reached its peak, around 2,100 computers were put to use for rendering.

In the film's 2,103 shots, special-effect scenes account for up to 1,838 shots, or 87.4 percent of the entire runtime.

Recalling his career beginnings as a live-action film editor, Zhao said he has discovered his passion for animated, propelling him to take up work in Light Chaser since 2013.
