Give a scientific and standardized definition of "Chinese herbal pieces". Chinese herbal pieces refer to the finished products that are specially processed under the guidance of Chinese medicine theory and according to the needs of syndrome differentiation and preparation. The drugs used to treat diseases in TCM clinic are Chinese herbal pieces and Chinese patent medicines, and the raw materials of Chinese patent medicines are also Chinese herbal pieces, not Chinese herbal medicines.

Some people confuse Chinese herbal medicines with Chinese herbal pieces. There are indeed some varieties of Chinese herbal pieces and Chinese herbal medicines that are not very different, or have the same or similar appearance, but they are essentially different. This difference is like boiled eggs and raw eggs, which are similar in appearance but different in essence. However, there are also some individuals who are completely consistent. For example, there is no such difference between Chinese herbal medicines and Chinese herbal medicines, but "Chinese herbal medicines" are mostly processed and have qualitative differences. So Chinese herbal medicine can't be called Chinese herbal medicine, but it can be used to explain what Chinese herbal medicine is.
