The "Double-Line Bamboo Drum Teapot" takes bamboo as its subject matter, with restrained dynamic movement, rhythmic cadence, and dignified elegance. The bamboo leaves are simple yet refined, upright and composed. During production, first beat out the base clay sheet and shape it into form, then prepare the clay coils and other materials. After the body cylinder is assembled, first attach the false bottom, then the main bottom, followed by cleaning the false bottom and the main bottom. Next, use the diligent tool to refine the main bottom to specification. Once the main bottom is properly shaped, attach the line strips and promptly clean the lines, after which the false bottom line strips can be opened. After the body cylinder is completed, install the spout and handle—install the handle at the seam point where the body cylinder joins, and install the spout on the symmetrical opposite side. When the clay reaches the appropriate dryness and moisture level, roll out the branch stems, then use a pointed knife to apply decorative leaf appliqués to the teapot body. Regarding this, Gu Jingzhou had his own unique perspective: > (Flower ware) draws its forms from nature, but must never be rigidly copied. Rather, it must be refined and artistically processed, not completely replicated. Tree stumps and bamboo nodes can be many or few, but there is one standard: they must possess strong expressive power. > > The growth pattern of bamboo is five leaves to one shoot, because when a new shoot emerges, the sixth leaf naturally falls away. In painting techniques as well, there is only the principle of five leaves. Applying bamboo leaves and bamboo nodes requires specialized tools—generally one needs a knife for applying bamboo leaves and a bamboo-made tooth tool. The pointed knife applies the bamboo leaves, the tooth tool rolls the bamboo stems, curls the leaf corners, and presses in the bamboo nodes.[1] --- [1] Gu Jingzhou's lecture, organized and recorded by Xu Chiping: *Technical Course Preparation Notes*, see Appendix 2 of this book, "Lesson Sixteen."
