Nian Qiuyan, 24 years old, is a designer of anti-corrosion glaze dot coating on the inner wall of retro enamel cups. She stubbornly believed that sparse hand-glazed dots allowed the enamel cup to breathe. The old factory was about to be renovated, and what she was waiting for was her first love Jiang Yan - now he is the most stringent food safety expert at the Light Industry Research Institute, and he wanted to shut down her handmade line with the national standard of "full glaze and full coverage". The two repeatedly saw each other between "anti-corrosion" and "nostalgia", and every craftsmanship point opened up old wounds. When the boiling water washed away the glaze and rusty water seeped out of the bottom of the cup, they saw clearly: the enamel protected the cup body, and the young people protected each other. But rust starts from within, and so do lies.
