If you travel to Hejin, there are many interesting tourist attractions, such as Yumenkou, Yuncheng Salt Lake, Jiulong Park and so on. Yumenkou, also known as Longmen, is located in the Yellow River Valley, 1/2 km northwest of Hejin City. The ancients had the admiration of "three waves in Longmen, one thunder in the flat land", which shows how majestic the surging waves of the Yellow River are here. The Tang poem "Wan Li Roars and the Longmen Surges" vividly depicts the spectacular scene of the Longmen Three Waves. The Yellow River flows through Yumenkou and is confined between mountains and canyons. The closer to Longmen, the narrower the riverbed. The rushing Yellow River, subject to the canyon, flew into a rage, rampaged and thundered, but it was squeezed into the riverbed by a quiet mountain canyon, collapsed to the Longmenkou at the end of the canyon, made a sharp turn and crashed into a cliff. It growled and flew out of layers of snow waves, turned around, fought back against the boulder on the other side, roared again and flew out of layers of snow waves. Back to the huge reef island in the river bed, it roared wildly again and sprayed water columns into the sky. After a loud noise, it fell trembling from the air to the bottom and jumped out of the dragon gate. These three waves of Longmen are the wonders of the Yellow River for thousands of years, which have aroused the poetic feelings of countless literati. Today, a new railway bridge, a highway bridge and a railway bridge have been built in Longmenkou, connecting Qin and Jin provinces. Three bridges span the Yellow River side by side, such as three volley rainbows, adding extraordinary momentum to Longmen. There are also salt lakes, which combine the magic of the Dead Sea with the unparalleled scenery of the Dead Sea. Here are abundant aquatic plants, dense reeds, birds and flowers, and full of vitality. The lake is criss-crossed, with countless islands wrapped in white, blue waves and sparkling water. The wonders of Bank of China Island in the lake are piled with nitrate all year round, and from a distance, it looks like a snowy mountain. Dozens of migratory birds live in dozens of square kilometers of wetlands around salt lakes all the year round. When people come to Yuncheng Salt Lake, they can not only enjoy the black mud bath and salt water floating in the Dead Sea, but also enjoy the beautiful scenery of the salt lake, explore the mystery of China salt culture in amusement and improve their cultural literacy. Yuncheng Salt Lake is really a rare tourist attraction integrating culture, fitness, tourism, entertainment and leisure. I hope you like it.
