The land of Shuangyashan has been cultivated by human beings since the Neolithic Age. It belonged to the Sushen State in the Western Zhou Dynasty (11th century BC-771BC). This area is also where the ancestor of the Qing Dynasty (1644-1911) emperors set up the first empire. During the Chinese Anti-Japanese War in the early 20th century, it was occupied by the invaders. After the new Republic of China was established, a coal mine agency called Shuangyashan was set up there. Then in 1966, it became a prefecture-level city under the direct guide of Heilongjiang. Winter lasts for a long time and the weather is dry and cold. The annual average temperature of the coldest month January is about minus 18C (minus 0.4F). Summer is short, rainy and hot. July is the hottest month with the average temperature of 22C (72F). Summer and autumn are best time to visit Shuangyashan, when it is warm and humid.
