Introduction to qigong:
In Poems on Books, Qi Gong described his process of understanding pen and ink: he understood the diversity of things better than Shu Dong; At first glance, he felt ordinary and had a sense of contempt. When I was in my twenties, I studied Tang steles, but I couldn't figure out how to get in and out. Learning from Zhao, I gradually understood my love for pen and my interest in ink. Looking back at Shu Dong, we can only know its joys and sorrows. Guy used to be used to the strengths of various schools, so he naturally came out without distortion. By studying cursive script again, we can know that Dong Yu's posting skill is not under Xing Ziyuan and Wang Juesi. In his early years, Dong Shi studied small letters in stone carvings, such as declaration forms and Huang Tingjing. After seeing the ink in the Tang Dynasty, he realized the brushwork and the way of ink painting, which is common in books and inscriptions. So I asked for advice from the traces of Tang people in Dunhuang stone chambers, studied and pondered, and made some progress in calligraphy, which is also because of this. He gradually learned the feeling of using a pen and his interest in ink from the calligraphy of Dong Qichang, Zhao Mengfu and Mi Fei. He found that Dong Qichang "began to understand the brushwork and brushwork" from the ink of the Tang Dynasty, and got inspiration from it, so he learned from the Tang Dynasty in Dunhuang Stone Chambers and made some progress in calligraphy.
