Peace grass is a kind of sacrifice and reverence in ancient times. It is regarded as a sacred plant and widely used in commemoration and mourning activities. In Zuo Zhuan, "Autumn and July, the grass dies and collapses." Records show that the death of Ping An Cao is closely related to social unrest. There is a similar record in the Book of Rites, in which the grass of peace is sacrificed to the gods to protect the peace and health of the family. Therefore, safe grass not only represents the efficacy of Chinese herbal medicine, but also has profound cultural connotation.
Peace grass is also widely used in modern culture, often as a symbol of "peace" and "blessing", meaning peace and happiness. For example, during the New Year, people will put some safe grass at home, so as to make their families healthy and all the best in the new year. At the same time, safety grass is also a common design element in production, commerce and other fields, and is often used in decoration, printing, cultural propaganda and other occasions. This emphasis and application of safety grass reflects the society's desire and pursuit for a harmonious, safe and happy life.
