Yuzhou is a distribution center for Chinese medicinal materials. Historically, there were more than 20 guilds and numerous medicine shops, medicine companies, medicine sheds, and drug stores, which promoted the development of Chinese medicinal material planting, processing, and preparation technology. The preparation of Chinese medicinal materials in Yuzhou began in the Ming Dynasty. It is a collection of skills from past dynasties. It is tailored to the medicine, with unique skills, fine production, and emphasis on efficacy. It has formed unique local characteristics in terms of "immersion, soaking, forging, stewing, frying, roasting, steaming, and boiling." There is a saying in the industry that "medicine is not as good as Yu." The Chinese medicine preparation skills of Yuzhou have a great influence throughout the country. In the early Qing Dynasty, Yuzhou's Chinese medicine preparation created five methods of steaming, soaking, slicing, pounding, and chopping. According to the shape of the medicine and the needs of the medicine, the pharmacists can process it into bites, segments, blocks, silk, thin slices, thin slices, pounded slices, planed slices, top blades, oblique slices, and discs. There are 14 kinds of slices (shapes), including fragrant slices and butterfly slices.
