When did Chinese painting begin to use the combination of poetry, calligraphy and printing?

The combination of poetry, calligraphy and seal is gradually formed in the development of Chinese painting. There were few inscriptions before the Song Dynasty, but the author's nickname was written in an inconspicuous corner. At that time, although there were poems and paintings, they were not written on the screen. It was not until the Song Dynasty that some poets and calligraphers began to inscribe or write poems on their paintings. In this way, poetry, calligraphy and painting began to combine, and literati painting began to sprout in the historical development of Chinese painting. Literati painting is a proper term in the history of Chinese painting, which generally refers to the paintings of literati in feudal society in China, so as to distinguish it from the paintings of folk painters and court painters. In the Yuan Dynasty, with the continuous development of literati painting, seals joined the ranks of poems, books and paintings, so poems, books, paintings and seals were as inseparable as four pairs of twin sisters. As soon as this art form appeared, it was widely adopted by painters at that time. During the Ming and Qing Dynasties, literati painting monopolized the painting world, and the artistic form of combining poetry, painting, calligraphy and printing became more and more perfect.
