Mount Lu or Lushan, officially named Mountain Lu National Park, is a mountain in China. It was also known as Kuanglu in ancient times. It is situated in Jiujiang in Central China, and is one of the most renowned mountains in the country. Mount Lu is located primarily in Lushan county-level city in Jiujiang Prefecture, although the northern portions are found in Lianxi District which was formerly known as Lushan District and until 2016 covered the majority of the Mount Lu. The oval-shaped mountains are about 25 kilometers long and 10 kilometers wide, and neighbors Jiujiang city and the Yangtze River to the north, Nanchang city to the south, and Poyang Lake to the east. Its highest point is Dahanyang Peak, reaching 1,474 meters above sea level, and is one of the hundreds of steep peaks that towers above a sea of clouds that encompass the mountains for almost 200 days out of the year. Mount Lu is known for its grandeur, steepness, and beauty and a prominent tourist attraction, especially during the summer months when the weather is cooler in the mountains than elsewhere.
