In particular, it is required to master the key technologies such as "hanging silk" and "dripping water into beads" in the oil refining process, the "tenderness" of the ointment, and the "chrysanthemum heart copper gong edge" in the ointment spreading process. Zhu Yangxin's traditional plaster making skills are passed down from mouth to mouth by the inheritors. His descendants have always adhered to the business philosophy of "focusing on traumatology" and the ancestral motto of "diligence and diligence", carefully inheriting and protecting traditional plaster products and production skills, and constantly making them more refined and stronger in the field of specialties. Zhu Yangxin's traditional plaster making skills have outstanding traditional Chinese medicine value, cultural value, folklore value and social value, and are a precious heritage of the motherland's traditional Chinese medicine culture.
