Its highest point is the Dahanyang Peak (1.5 km above sea level). The mountain is a prominent tourist attraction, especially domestically.庐山坐落于中国江西省九江市，鄱阳湖边。它的最高点是大汉阳峰（海拔1500米）。庐山是中国境内的主要旅游景点。The northwest slope is where Hui-yuan founded Pure Land Buddhism in 402, and features the Donglin Temple. 山的西北侧有慧远（音译，你自己查证一下）于公元402年创建的东林寺。Lushan National Park is a UNESCO World Heritage Site (cultural) whereas Lushan Quaternary Glaciation National Geopark is a member of UNESCO Global Geoparks Network. 庐山被列为世界文化遗产，并入选世界地理公园。The Lushan Botanical Gardens features tens of thousands of plant species. Below the Five Old Men Peak is the White Deer Grotto Academy, named after the poet Li Bo(Chinese: 李渤) (not to be confused with the famous poet Li Bai), who raised white deer there. It is amongst the oldest institutes of higher learning in ancient China. 庐山植物园有上万种植物。West is the Flower Path which provided inspiration to Bai Juyi, a famous poet who lived during the Tang Dynasty. Between the Yangtze River and Lake Poyang lie the Greater and Lesser Tianchi Lakes, the Jingxiu Valley, and Lulin Lake. On the north bank of the latter is the Lushan Museum, which features pottery and bronzes dating from various periods of ancient China, as well as calligraphic works from the Tang Dynasty and paintings from the Ming and Qing dynasties. At the centre (between three peaks), and at an altitude of over 1 kilometer above sea level, is the town of Guling, which is linked by a mountain highway to neighboring spots in the region. 对庐山的景点不是很了解，翻起来好累。后面部分你查查中文网站，自己翻译一下吧。
