Introduction to Niu Nostrils: There are two villages in Laoniuwan, one in Inner Mongolia and the other in Shanxi. They are separated by a deep ditch in the middle. Due to the increase in reservoir water level and the backflow of river water, the water in the ditch is 30-40 meters deep ( (The water level will change in different seasons), you need to take a local farmer's boat to cross. Laoniuwan Village on the Inner Mongolia side is recognized by photographers as the best location to take panoramic shots of Laoniuwan. The hillside shaped like a cow's head is located on the Inner Mongolia side. Here you can see a famous natural landscape - the cow's nostrils: There are two holes on the cliff. There is also a naturally formed cave on the side of the cliff. Through the cave, you can see the bend of the Yellow River under the cliff. The scenery is magnificent and beautiful.
