Give me all the information about Hengshan and Songshan.

Poems praising Hengshan:. "The people in Hengshan Mountain are black and purple, and the elders in Antarctica see from below", "Zhu Rong rises from the ground and disappears in the light smoke", "The blue sky and stars are close from top to bottom, and the world of mortals is far from bottom".

A poem praising Hengshan: "There are five mountains in heaven and earth, and Heng Yue lives in the north. The strange stones are stacked on the Wan Li, which is bizarre and unpredictable. " "The path of vegetables is difficult to jump, and there is still a ladder in the volley, slowly reaching the blue wall and blending with the real white clouds." "Gan Kun has his own spiritual realm, and his status is not equal to other mountains."

Praise Songshan's poem: "The dusk belongs to Song Cen's purple smoke, and the 36 peaks are long." "If Yin is the master of Songshan Mountain, the thirty-six peaks should be laughed at." "The full moon, the Mid-Autumn Festival in Songmen, Xuanyuan early in the fog; Shui Ying plows Tian Ge in spring and avoids summer harvest in summer; You can drink by the stone river and fish on the Yuxi stage; There is less rain and less room to watch the sunny snow, and the ink waves flow in front of the waterfall cliff.
