"Sikuquanshu" and "Chenzhou Tongdian" were released in Chenzhou, Hunan. The book is divided into four parts: classics, history, zi, and collection.
It compiles the extant works from the Tang Dynasty. Many Chenzhou classics have been lost long ago. Those that still exist are scattered in various collections or private hands, making it inconvenient to consult and study. It has made a contribution to the "protection and utilization, protection and development" of cultural heritage model.
