Yao medicine bath has a long history. Most Yao people living in Dayaoshan live on high mountains, with frequent migration and difficult living conditions. However, the deep mountains and old forests are rich in medicinal resources. The brave and industrious Yao people have rich experience in using local drug resources to prevent and treat diseases, protect health and reproduce future generations. Without the national language, it is impossible to sum up rich medical and health experience and pass it on to future generations. Health-keeping custom (Pang Tong medicated bath) has become a special way of recording and spreading, and it is still used in Yaozhai, Dayaoshan.
