Excuse me, when was Old Town of Lijiang established?

Old Town of Lijiang suggested that the park be built in 1200- 12 10 (Southern Song Dynasty). After more than 800 years of prosperity, Old Town of Lijiang has gradually become the economic and cultural center of northwest Yunnan, providing good environmental conditions for the development of national culture. The Naxi people living here have created splendid national culture together with other ethnic minorities. No matter the streets, squares, archways, water systems, bridges, residential decorations, courtyard sketches, sills and stone tablets in the ancient city, they are permeated with the cultural literacy and aesthetic taste of the Naxi people, fully embodying the cultural connotation, artistic conception and charm of local ethnic religions, aesthetics, literature and other aspects, and showing the profound and rich contents of history and culture. In particular, Dongba culture, white sand murals and other traditional cultures and arts with rich connotations have left a brilliant chapter for the history of human civilization.
