After the Jingkang Incident, Zhao Gou went south from Hebei to the capital of Nanjing, Yingtianfu (Shangqiu, Henan), to worship at Hong Gongqing, Zhao Song's ancestral temple, and ascended the throne in the palace, changing the Yuan Dynasty to Jianyan. Established in the Southern Song Dynasty (1128-1279). Later, Emperor Gaozong of the Song Dynasty traveled all the way from the Huaihe River to the Yangtze River and then to Hangzhou. In the first year of Shaoxing (1131), Hangzhou was promoted to Lin'an Prefecture and designated as "Xingzai" (accompanying capital), which was actually the capital. The Jin Dynasty also rushed southward, approaching Lin'an. Song Gaozong had no way to retreat, so he had to escape into the sea and wandered along the coast of Wenzhou for four months.
