The growth of Cordyceps sinensis is very mysterious to most people. There used to be a poem: "Cordyceps sinensis is full of things, and change generates a breath." One thing can be planted at the same time, and the physics in the world is hard to be poor. "In fact, Cordyceps sinensis is a combination of insects and fungi. Insects are the larvae of Cordyceps sinensis, and fungi are Cordyceps sinensis fungi. Every summer, when the snow and ice melt on the snowy meadow above 3,800 meters above sea level, the little weaver moth will leave thousands of Qian Qian eggs on the flowers and leaves. Then the moth eggs turn into worms, drill into moist and loose soil, absorb the nutrition of plant roots, and gradually raise the body white and fat. At this time, the spherical ascospores meet the larvae of Cordyceps sinensis and get into the worm to attract its nutrition and germinate hyphae. The larvae infected by fungi gradually climbed to two or three centimeters from the surface and died from beginning to end. This is "Cordyceps sinensis". Although the larva is dead, the fungus in the body grows day by day until it fills the whole worm. In the late spring and early summer of next year, a purple grass grows on the head of the worm, which is about two to five centimeters high and has a pineapple-shaped capsule at the top. This is "summer grass". At this time, Cordyceps sinensis is the most developed and has the highest effective components in the body, which is the best collection season. Diqing and Nujiang in Yunnan Province are one of the main producing areas of Cordyceps in China.
