This is a series of scent-based installation works by Wang Changcheng. Following the brewing distillation process, he steamed sorghum and mixed it with fermentation starter, rice husks, and saccharifying mold, then placed them into an elderly urinal that had been transformed into a fermentation vessel. The fermentation process was monitored through an electronic thermometer and a U-tube for fermentation gases. Once fermentation was complete, the rubber urine collector could be used to smell the fragrance of the alcohol.

This series attempts to discuss the motivations behind filial piety while questioning the notion of its stability and permanence. It also presents the idea that filial piety is related to food surplus and the appearance of alcohol. Only when food is abundant enough to ferment can we sustain filial piety.
