‎________________________________________________________________________‎ ‎________________________________________________________________________‎ ‎________________________________________________________________________‎ Mountain Changbaishan Changbaishan means eternally white mountains.It is China's largest nature reserve and is home to the rare Manchurian tigers，snow leopards and wild ginseng.As a dormant volcano，Changbai Mountain boasts rare animals，marvelous lakes，amazing hot springs，and forests that stretch to the horizon.There is splendid scenery during the four seasons，but it is especially beautiful in winter.‎ Covering a total area of 2000 square km，Changbai Mountain Nature Reserve is，as a mammoth natural zoo and botanical garden，part of the UNESCO'S Man and Biosphere Program.‎ During the peak seasons，namely June through September，hundreds of flowers blossom on the Southern and Western slopes.It is very cool in Changbai Mountain，so it's an ideal place for escaping from the summer heat.But it is also very rainy in July and August，and visitors cannot watch the Lake of Heaven clearly at that time.‎ Changbaishan is a volcano lying between China and North Korea.It is about 2800 meters ‎ high.Located in the counties of Antu，Wusong and Changbai in southern Jilin Province，Changbaishan is one of China's nature preservation zones，covering an area of over 200 000 hectares，extending 78.5 kilometers north to south，and 53.3 kilometers west to east.It has a wholesome natural environment and ecosystem with world－famous precious animals like Northeast tigers and sables.It's China's typical comprehensive nature existence of world importance.‎ The Crater Lake：It nestles on Baitoushan(The White－Head Mountain)，the main peak of Changbaishan and is also a border lake between China and Korea.Surrounded by 16 exotic peaks，the lake is the crater of a volcano，filled with blue waters，known as Tianchi—the Lake of Heaven.The basin－shaped lake,2155 meters above sea level，and 313 meters deep at maximum，encompasses an area of 9.2 square kilometers.It's a typical high mountain lake.The lake waters keep flowing out，without causing apparent change in its water level.The two white rivers of the upper reaches of the second Songhua River originate here.The inner side of the lake bank is craggy cliffs formed by rough－surface rocks and white pumice stones，which make the lake resemble a marble bowl carved with uncanny workmanship.The surface of the lake is smooth as a mirror，with the reflections of grotesque cliffs upon it in numerous exotic shapes.‎ The Waterfall of Changbaishan：The water of Tianchi finds its way out through an opening in the northern bank and at a vertical cliff,1250 meters away，drops 68 meters down with loud rumbles.The Changbai Waterfall hangs in the air like a white ribbon.‎ The Hot Springs of Changbaishan：At the north side of the White－Head Mountain，there is a group of hot springs covering an area of over one thousand square meters.Two white rivers wind their ways among the hot springs.The right banks where the mouths of springs concentrate are shrouded in hot misty air all the year round.The springs vary in temperature，with the highest reaching 82 degrees Celsius.The hot waters have high medical value.‎
