| come from Huzhou, a small lakeside city in southern China whose economy heavily depends on the lead-acid battery industry. My hometown produces most lead-acid batteries in China, leading to countless factories along the entire industry chain, from upstream to downstream. My father is one of the practitioners in this industry, with nearly 20 years of experience. Inspired by the theme of 'batteries,' I have created a short film that merges my perception of my father and his profession.
