Mr. Jin Duo was born in Xiaoxian County, the hometown of calligraphy and painting in China. He was influenced by the environment in his childhood and loved calligraphy. He used the yellow river beach as paper and dry branches as a pen, starting with Tang Kai, attacking Yan (Zhenqing) and Liu (public rights), going to Ouyang (Xun) and Chu (Sui Liang), and then learning Wang Xizhi's Preface to Lanting. After college, he loved Mao calligraphy. With his quick artistic thinking, persistent perseverance and pure creative mentality, he devoted himself to studying Mao calligraphy for more than forty years, and won the essence of Mao calligraphy, forming a bold and unrestrained artistic style. The works seem to be eclectic, but in fact, they learn from others' strengths and have profound traditional calligraphy skills. Their magnificent brushwork, superb and unique layout have reached a perfect state, and they have become the leader in the "Mao-style" calligraphy art and are praised as "the first person in Mao-style calligraphy" by the calligraphy circle.
