When people are in harmony, the water flows eastward, representing a continuous force. In calligraphy, human voice is often used to describe the form of water, such as rivers, lakes and seas, even waterfalls and springs. Such calligraphy works often give people a broad, profound and free feeling.
As a special heavenly stems and earthly branches group, Renyin is widely used in calligraphy creation. Calligraphers can not only use it to express the form of water, but also change the method and layout to express the power of "endless flow" represented by the combination of non-yin and non-yin. In this way, Ren Yin's calligraphy works are not only intoxicated with its aesthetic feeling, but also make people feel the never-ending philosophical meaning of the stream of life.
