Where is the political, economic and cultural center of the Southern Song Dynasty?

The political center and economic and cultural center of the Southern Song Dynasty was Lin 'an (now Hangzhou, Zhejiang).

After the Song Dynasty moved south, it officially made Hangzhou its capital and promoted Hangzhou to Lin 'an Prefecture. Hangzhou has become the national political, economic and cultural center, providing many favorable conditions and opportunities for the development of the city. The process of moving south has prompted a large number of northerners to live in Hangzhou. Among these northern immigrants, there are not only royalty, nobles, officials and rich gentry, but also a large number of skilled craftsmen engaged in agriculture, handicrafts, commerce, catering services and other industries. They settled in Hangzhou, which greatly promoted the development of Hangzhou's business form.
