The close combination of calligraphy and Chinese painting has become a fashion of the times. Which dynasty did it originate from?

Yuan dynasty. According to relevant public information, the Yuan Dynasty was an important period for the development of China's calligraphy and painting. Because the rulers of the Yuan Dynasty came from northern Mongolia, and the Yuan Dynasty didn't recognize Chinese culture enough, it was more tolerant of multiculturalism in painting and calligraphy. This multi-cultural tolerance and integration provides conditions and space for the combination of calligraphy and Chinese painting.
