Songshuping

　　  This is a rare primeval forest community in the mid-latitude regions of the Earth, with the main tree species being the Qinling fir, a Class III protected plant in China. In addition, scattered trees such as the Chinese plum yew and the yew can also be found here.   

　　    The spacing between trees in Songshuping ranges from 3 to 5 meters, and the average age of the trees is between 300 and 400 years. Many trees in the forest grow side by side and are referred to as “sister trees” or “joined branches.” Their trunks are covered with moss, and there are very few lateral branches or leaves below ten meters, often entwined with green vines climbing upward. The forest also has fallen giant trees, some of which remain lush with foliage, while others have died and are now covered with fungal plants. The forest floor has a thick layer of humus that feels spongy underfoot.   

　　    While walking through the forest, you may occasionally come across rare medicinal herbs such as the "head-top pearl" and "Emperor Wen’s single writing brush."
