Compared to the north slope of the rock formation, the west slope of Changbai Mountain is the best area to watch the Tianchi. The development of Xipo is later than the northern slope, and the commercial atmosphere is much less. From the mountain gate, take the scenic bus, Mercedes-Benz in the thick broad-leaved forest, in the late autumn sunshine, red and yellow leaves light the autumn colors. In the face of the steep tiger's back ladder, more than 1,000 steps are waiting for us to conquer. The road to the mountain is not boring. The vertical distribution from the coniferous and broad-leaved mixed forest to the coniferous forest, Yuehualin, and low shrubs is a living geography book.

The clouds are flying around, and the surface of the water seems to rise up.
