The series “Original Rhythm” is based on Tzeng Yong-Ning’s observation and concern for nature, which is transformed into exploring his inner spirit. The circles in the paintings have the meaning of “originality”. By extending, overlapping, and reproducing the circles, the artist wants to portray the importance of humans coexisting with nature. Through tens of thousands of ball-point pens, Tzeng was able to paint the circles on the large-scale canvas, representing his personal growth.
