Erlongshan, also known as Yumen, is located 30 kilometers north of hancheng city, Shaanxi Province. According to Gong Yu, "As for the Longmen, the river guides the stone." According to "Famous Mountain", "When the river reaches this mountain, the water waves rise and fall, like a mountain boiling". Qing Qianlong's "Hancheng County Records" contains: "There are broken mountains and cliffs on both sides of the strait, which are relatively like doors, but dragons can cross them, so they are called Longmen." According to legend, "Longmen" was carved by Dayu when he was in charge of water control, also known as Yumendu. Regarding "Yu chisels Longmen", Lv Chunqiu said: "Diligent in the world, unremitting day and night, connecting with Dachuan, absolutely blocking, chiseling Longmen." "Three Stories Meeting" records: "There are two mountain walls here, from which the river flows out, competing for about a hundred steps. The walls on both sides are cut off and shaped like doors, so it is called "Longmen".
Near the "Longmen", there are traces of Xu Duoyu. In the big river south of Longmen, there is the so-called "Yu Wangling", which is above the water and looks like a sandbar. Although water has been pounding, it can't be submerged. Legend has it that when the cliff was cut, the boulder fell into the middle stream, sank to the bottom of the water and solidified into a hill, which was the place where the construction was commanded, not the "Yuwangling". There is also a stone in Yumen water, engraved with the word "Longmen", as big as a bucket, and people will see it when they reach the bottom; When the river rises, the stones sink. I don't know the author's name and the date of engraving.
Longmen is the throat of the Yellow River, the second largest river in China. Longmen Mountain straddles the banks of the Yellow River, with high mountains facing each other, cliffs standing on the wall and huge waves roaring. Xiyumen Mountain is 892.6 meters high and Dongyumen Mountain is 89 1 meter high. The terrain is very dangerous. The winding Yellow River runs down from the Kunlun Mountain with continuous snow peaks. Along the way, Wanxi met, screaming, crossing the canyon, getting deeper and deeper, and heading straight for the foot of Longmen Mountain. Here, the mountains on both sides of the strait overlap, the rivers are swift and swift, and the risks are unpredictable, giving people a sense of adventure like being on a cliff and moored in a deep pool. One of the eight scenic spots in Hancheng, the so-called "Spring Wave at Yumen" refers to this place.
There is a Temple of Danger on the East and West Longmen Mountains. The Western Regions Temple in Yuan Shizu was built in the early Yuan Dynasty? AD 1264。 Magnificent buildings, standing on the mountain, pavilions, steep, beautiful and elegant, carved with beams and painted with buildings, are gorgeous and unusual. Standing in front of the temple, I was deeply moved by the vivid expression of the ancient poem "The Yellow River goes straight to the sky and two mountains suddenly open". Every March, people from Shanxi and Shaanxi gather here to trade materials, which is very lively.
"Longmen", mountain to mountain, with the Yellow River running in between. The waves are rough and roaring like thunder. Therefore, the ancients had a beautiful sentence of "Yumen is three levels deep and minefield". Longmen Scenic Area is really a miracle of the world. There is a myth in the story of Sanqin: Every March, when the ice and snow melt, there are yellow river carp leaping from under the Longmen of Baihe River. Less than seventy-two carp can leap into the dragon gate in a year. As soon as you climb the Longmen, the clouds and rain will follow, and the sky will burn its tail and turn into a dragon; If you can't climb the dragon gate, just point your forehead and show your cheeks? Refers to the amount of damage. "Because it is not easy to climb, it is valuable. In the past scientific era, people who were famous for their gold medals were called "yue longmen", that is, "once on the Dragon Gate is worth ten times".
Longmen Mountain is high, towering into the sky, steep and steep, and the Yellow River is tightly sandwiched in the middle. The narrowest place is Longmen Pass, which is only 60 meters long and looks like a doorway. Here, the torrent rushes to the shore, and the waves splash and spin together, and the sound is like thunder. As soon as the water comes out of the estuary, it pours thousands of miles, and the four fields are open, just as Li Bai, a great poet in the Tang Dynasty, sang, "The Yellow River comes from the west to set Kunlun, roaring Wan Li and touching Longmen."
