Pu Songling once wrote a poem () with a vivid name.

Pu Songling once wrote a poem, "The name (Cordyceps sinensis) is substantial, and change produces a kind of harmony. One thing can be planted at the same time, and the physical trust in the world is endless. "

This is a poem about the growth of Cordyceps sinensis written by Pu Songling, a famous writer in Qing Dynasty, when he was a private school teacher in the countryside. It can be seen that the ancients worshipped and marveled at Cordyceps sinensis.

The reason for the formation of Cordyceps sinensis is that on the Qinghai-Tibet Plateau, the larva of a spotted butterfly hides in wet and warm soil for the winter. When the mycelium of Cordyceps sinensis enters the larva of this butterfly, the larva will die, and the larva's body will gradually evolve into the shape of grass above and insects below.

Cordyceps sinensis has a very good curative effect and now it has a high market value.
