What is the relationship between calligraphy and landscape painting?

Calligraphy and landscape painting are only available in China. China had a high civilization in ancient times, and knew how to use brush and Hui ink long ago, which was not available in other countries at that time. Landscape painting is also a kind of Chinese painting, ranging from flowers, birds, insects and fish to mountains, rivers, lakes and seas, all of which are copied with pen, ink, paper and inkstone, and even the words are expressed in the form of art, so China's calligraphy and landscape painting have high attainments since ancient times. My calligraphy teacher often says that "painting and calligraphy are one family" and "painting and calligraphy are of the same origin". It is natural to think that the relationship between painting and calligraphy is like this. I think so, too. If you like painting and calligraphy, we'll talk about it in detail when we have time.
