　　The black fungus produced in this town not only has delicate texture, crisp tenderness, and delicious flavor, but is also rich in nutrients. It contains minerals such as selenium, iron, phosphorus, potassium, magnesium, and calcium, as well as various vitamins and amino acids. With high medicinal and health value, it is considered top-quality among black fungi. Widely praised by consumers as the "gold of foods," it is aptly named: Golden Black Fungus.
