Hangzhou, as early as the Five Dynasties and Ten Kingdoms period, was the capital of Wu Yue State. At the end of the Tang Dynasty, the world was in chaos. At that time, Qian Liu, the secretariat of Hangzhou, was divided into the southeast corner. In the first year of Kaiping (907), the late ruler Jin Liang made Qian Liu King of Wu Yue. Wu Yueguo is divided into thirteen states, one army and eighty-six counties, with Hangzhou as its capital, and has been founded for nearly a hundred years. Later, Zhao Kuangyin unified the whole country and established DaSong, and Wu Yueguo was also a subordinate. After the Jingkang Revolution, the Song Dynasty moved south and the Southern Song Dynasty was hastily established. In May of the second year of Jingkang, Zhao Gou, the son of Song Huizong, a "Kang Wang" who went abroad, boarded Yingtianfu (now Shangqiu City, Henan Province) and changed his country name to "Jian Yan" (1 127), which was the beginning of the Southern Song Dynasty. At that time, there were three opinions on the location of the capital: Li Gang, an anti-Japanese faction, advocated the "three capitals" of West Chang 'an, South Xiangyang and East Jiankang; Anti-gold star Zong Ze advocated sticking to Tokyo; Wang Boyan, a capitulator, proposed "patrolling the southeast". Later, due to the lack of military strength, Zhao Gou had to cross the river south, first settled in Zhenjiang, and then fled to Hangzhou. Later, in the first year of Shaoxing (1 13 1), Yuezhou was renamed Shaoxing Prefecture for the first time. Soon I decided to move the capital to Hangzhou and change my name to Lin 'an. The name means "temporary settlement". One day I will fight to the north and return to Tokyo.

After Lin 'an became the capital of the Southern Song Dynasty, a large number of northern bureaucrats, landlords, monks, businessmen and people fled to the south and poured into Lin 'an. At that time, the population surged to over one million, making it the largest city in the world in the 12 century.
