Aershan is full of wonders, if the most exotic is the Shitang forest. The Shitang forest is 20 kilometers long and 10 kilometers wide. It is a geological remnant of magma flow after many volcanic eruptions in the Quaternary. There are boulder, lava, lava rope, jet butterfly, lava hill, jet cone, lava valley. The magical landscape such as the underground dark river is called the Volcanic Geology Museum. The soil in Shitang is thin, but there are tall and tall Xing'an larch, alpine cypress, cypress pine, green and green, and Jinxingmei and Yinxingmei are unremitting, and there are large pieces of low-lying plant moss. In the Shitang forest, the stone and the forest are in harmony, the flowers and the grass are merged, the clear stone creek and the quiet water pool are hidden. The jumping stone rabbits sometimes make a crisp sound, which constitutes a strange and lively and dynamic. A natural picture that is ingenious.
