The book "Practical Course of Famous Pen Calligraphy: Wu Yusheng Xingkai" follows the learning principles of "easy first, difficult later" and "step by step", starting with common sense of calligraphy, gradually learning the basic strokes, radicals and frame structure, and finally learning the works. Each copybook will enable you to complete the systematic learning process from entry to mastery, from practice to application, and help you achieve the best results in the shortest time. In addition, we also set practical and interesting contents in the copybook, such as "calligrapher's experience", "book anecdotes", "calligrapher's quotations" and "knowledge posts", which not only broaden your horizons, but also alleviate the boredom caused by practicing calligraphy. This copybook has made a great breakthrough in function. In order to meet the actual needs, we have added the function of temporary writing in addition to the functions of red drawing and shadow drawing, and organically combined the three methods of description and temporary writing to meet the requirements of practice to the maximum extent. It can be said that this set of copybooks will be a rare practical writing model for beginners and calligraphy lovers, and will be widely welcomed by everyone to help them receive the best effect of practicing calligraphy in the shortest time.
