Qian Peiyun and Mi Zhong are different people. Qian Peiyun is the author of Xuan Ming Hard Pen. He printed five classic family instructions, such as Zhuge Liang's Commandments, Yan Jiaxun, Zhu Zi's Family Instructions, Disciples' Rules and Zeng Guofan's Family Instructions, and attached simplified characters to the back of the book. These works show the talent and attainments of hard pen calligraphy. Xuan Ming is a calligraphy brand, which is related to Qian Peiyun, but it doesn't represent him. Xuan may have created a calligraphy brand based on his works or styles to promote and display related calligraphy works.
