In the southeast of Jimo, there are 100 miles of mountains, the highest of which is Laoshan Mountain. Among the many peaks in Laoshan Mountain, Giant Peak is the highest. There is a hole at the top of the Giant Peak called Baiyun Cave. This hole is far-reaching and bright, and there is spring water beside it, so you can rinse your mouth and wash your hands. There is nothing like it in the mountains around the Giant Peak. Even on a sunny day, the clouds on the mountain will become almost unrecognizable and disappear without a trace in an instant. But in a cold place, there are many strong winds, and people who are not strong and determined dare not stay for a long time. Climb it and climb vines along the cliff, winding for dozens of miles. If you don't have a special interest in mountains and rivers, you can't get to this place. People in Beiquanshan once played in the sea. They traveled to Yaoshan in the south, boarded Langxie Platform, and watched Zhifu Mountain in the north. These famous mountains are not as high as Laoshan Mountain. Qishan said, "Mount Tai is not as high as Laoshan Mountain in the East China Sea." This means that Laoshan Mountain is higher than Mount Tai. However, Laoshan is located in the cape area, and its reputation has not spread to the whole world. However, people know the names of Qushan, Langxietai and Zhifu Mountain because Qin Shihuang and Han Wudi visited here. Alas! People's knowledge is not easy to be known by others, let alone such things!
