他是上世纪煤矿大裁员时的一名普通下岗职工。面对求职受挫,他潜心研究汉字书写和教学,发明了坐标习字格,创造数码签名,获四项国家专利,还出版多部相关著作。他经常在北大、清华、天安门国旗护卫队等多所高校和部队免费讲课,却靠在街边摆摊为人设计签名维持生计。他就是中国硬笔书法协会常务理事、华夏书画艺术交流协会副主席——冷春华。 He was an ordinary laid-off worker at the time of the massive coal mine layoff in the last century. In the face of job frustration, he devoted himself to studying Chinese writing and teaching, invented the coordinate habitual character lattice, created the digital signature, won four national patents, and published a number of related books. He often gave lectures free of charge at colleges and military units such as Peking University, Tsinghua University and the Tiananmen Square National Guard, but set foot on the street to design and sign people’s livelihood. He is the executive director of China Hard Pen Calligraphy Association and vice chairman of China Calligraphy and Art Exchange Association - Leng Chunhua.
