Chang Leian entered the military camp from school and has been engaged in and in charge of the propaganda and cultural work of the army for more than 20 years, giving full play to and expanding his talents in music and calligraphy. After changing jobs, he entered Xi 'an Conservatory of Music to teach calligraphy. Chang 'an, an ancient capital with profound cultural accumulation, urges him to study hard, learn from each other's strengths and achieve harmony day by day. His calligraphy combines rigidity with softness, rigorous and changeable words, free and easy style, and quite masculine. His works have participated in calligraphy exhibitions in cities, provinces, the whole country and even at home and abroad for many times and won awards. Many works have been collected by China Art Museum, Great Hall of the People, National Cultural Palace and other national art units. He inherited this tradition, but he didn't stick to it. On the basis of studying brush calligraphy for decades, he replaced the pen with a needle, which formed a calligraphy art different from ordinary people and endowed China with a new form and character. Known as "a unique skill in China", it won the invention patent of the State Patent Office. When these colors flow onto the rice paper, they become words, and they become words. In one breath, he wrote 20 different forms of needle calligraphy works, such as Man Jiang Hong, Qin Yuan Chun Xue, nave's "Seeing a foot when something happens, observing its opinions with others" and cursive couplet "Painting birds to show their true meaning, and calligraphy overflowing with fragrance". Ups and downs, flickering, pressing and turning, all of which are full of the natural rhythm of calligraphy. Colleagues in the capital calligraphy and painting circles commented on his needle calligraphy, which is not only a Mohist fashion in the new century, but also a new form of traditional art, from which readers can taste the connotation and high-grade beauty of calligraphy art.
Chang Lei An wrote the charm of the brush with a hard pen, and wandered freely between the brush and the hard pen, which made the hard pen calligraphy change from a "small family" to a "beautiful woman", entered the palace of calligraphy art, filled the gap in the reform of calligraphy tools, and became a wonderful flower in Shaanxi book circle.
