　　Cultural Background

　　The history of harvesting and utilizing fungus in China dates back a very long time. As early as the 30s of the 6th century, the Northern Wei Dynasty agriculturalist Jia Sixie wrote in his book Qi Min Yao Shu (Essential Techniques for the Welfare of the People): “Wood Ear Pickle: Select those growing beside jujube, mulberry, elm, or willow trees, still soft and moist. Dried ones are not suitable. Oak wood ears may also be used. Boil them for five boils to remove the fishy juice, then take them out and place them in cold water to clean thoroughly. Then soak them in sour liquid to wash them out, finely slice them. Add a small amount of coriander and scallion whites—just enough for aroma. Add fermented soybean juice, clear soy sauce, and vinegar, adjusting the seasoning to taste. Add minced ginger and pepper. It turns out very smooth and delicious.” This describes in great detail the growth and consumption methods of fungus. Today, the uses of fungus are far more extensive than in the Northern Wei period. In Gansu Province alone, there are over a hundred dishes made with Kang County black fungus, making it a common delicacy at various banquets.
