One advantage of hard pen copying is that it can effectively improve students' observation ability. Hard copy requires strict observation of every detail of the original. This observation is not only helpful to calligraphy practice, but also helpful to many aspects of life. For example, in entertainment activities, learning to observe will bring a better experience.
Hard copy is not only a skill, but also a manifestation of spiritual understanding. When we copy slowly, we not only need to pay attention to sensibility and skills, but also need to relax our mentality and achieve a sense of artistic conception. This process is not only a kind of enjoyment of beauty, but also a manifestation of self-cultivation.
