First of all, for the practice of Xiao Zhuan, tracing red is of little significance and can be copied directly. For the study of official script, we can start with red painting. The reason for this is the following：
1, Xiao Zhuan is a kind of seal script, which is developed on the basis of the bronze inscription of Da Zhuan. After Qin Shihuang unified China, under the auspices of Prime Minister Li Si, on the basis of synthesizing other six languages, Xiao Zhuan unified, simplified and standardized a style, so it was also called "Qin Zhuan". Because the basic feature of Xiao Zhuan is that all strokes are uniform in thickness and basically unchanged; The font is slender and smooth. Therefore, the basic brushwork of Xiao Zhuan can be summarized by "central pen". In other words, the main front of the pen must be in the center of the painting so as not to be exposed. It is characterized by hiding the head and protecting the tail, which contains strength, because the strokes written by the central pen are concise, powerful, round and beautiful, and have always been regarded as the main method of calligraphy. Compared with other calligraphy styles, Xiao Zhuan's brushwork is relatively simple. In this case, tracing red is of little significance, and direct copying is the main practice method.
2. The situation of official script is different. Lishu, also known as Han Li. Its calligraphy is characterized by wide and flat fonts, long horizontal paintings and short straight paintings; Its strokes vary more than that of Xiao Zhuan, and it pays attention to "silkworm head and goose tail" and "twists and turns" horizontally. Its vertical, left, press, point, fold and hook have many different strokes and structures for different characters. Because the main purpose of tracing red is to learn the process of strokes, understand and master the basic brushwork and the changes of strokes. Therefore, Hong Miao can be familiar with and master these brushstrokes.
Finally, it needs to be pointed out that no matter what kind of writing style you practice, tracing red is only a transition in the primary stage, and it should not take too much time, and ultimately it depends on copying.
