Sparrow droppings cost more than meat, selling for over a thousand yuan per jin. Known in traditional Chinese medicine as white clove, well-preserved golden-white granular droppings fetch more than twenty yuan for three grams, equating to over one thousand yuan per jin. Some breeders in Quanzhou, Fujian raise thousands of sparrows not for meat or viewing, but for their excrement. Each bird produces tiny amounts daily; sheds yield mere dozens of grams, requiring drying, cleaning and grinding. Despite tedious work, competition for this business is fierce. Several crypto-trading acquaintances I know finance their trades by raising sparrows to harvest and sell droppings. In a sense, all 360 trades exist to serve the crypto sphere.
