He studied calligraphy under the guidance of his father since childhood and became a lifelong career. I worked as a bank when I was young, but I was happy to learn calligraphy. I traveled all over the country, consulted my predecessors in calligraphy, exhibited inscriptions and ink, studied Erwang, Huai Su, Ou Yangxun, Wu Dacheng and Huang Mufu, and my calligraphy level gradually improved.
