First of all, from the practice method, the practice method of Liupintang is considered to be better. Liupintang calligraphy practice method is divided into six steps, paying attention to step by step, which is very suitable for beginners. In contrast, Zheng Xi's calligraphy practice method lacks step division, and the effect of calligraphy practice is relatively not obvious.
Secondly, in terms of the quality of copybooks, Liupintang copybooks are considered as better quality draft paper, while Zheng Xi copybooks are of poor quality, using bamboo pulp paper.
Therefore, according to the above comparison, we can draw a conclusion that Liupintang's calligraphy practice method is better, but Zheng Xi's copybook quality is slightly insufficient. However, this does not mean that under all conditions, the effect of Zheng Xi's calligraphy practice is not as good as that of Liupintang. Under certain conditions, the effect of Zheng Xi's calligraphy practice may exceed that of Liupintang. For example, if Zheng Xi's calligraphy practice method is properly used, the effect may be better than that of Liupintang.
