Introduction to Zhuqianyu: Zhuqianyu is about 1,700 meters long and 380-750 meters above sea level. It is located in a deep valley in the east of Chunyang Slope. Above the ditch is the swing frame. Legend has it that Bixia Yuanjun of Mount Tai often came here to play on the swing. At that time, in addition to the two existing stone pillars, another one was horizontal. One day, the daughter of the Cu Lai Mountain God also wanted to imitate Grandma Taishan and swing up to Mount Tai on the swing. At this time, an old woman with silver hair said that she was not destined to swing on the swing. The stone pillar broke into many stones and rolled down from the top of the mountain. When the daughter of the mountain god looked back, she saw that the mother-in-law had long disappeared. It turns out that she is Grandma Taishan. Up to now, next to the stone pillar to the west of the swing frame, the daughter of the Culai Mountain God is still crying while holding on to the pillar.
