When did the laws and regulations of the Sui Dynasty come into being?

The laws and regulations of the Sui Dynasty were mostly collected from the Eastern Wei Dynasty and the Northern Qi Dynasty. In the first year of Emperor Wendi of Sui Dynasty (58 1), Gao Ying and Zheng Yi were ordered to delete decrees, and Emperor Wendi was ordered to change decrees, decrees, forms and forms for three years. From then on, laws, decrees, forms and forms were parallel, and the code system of China feudal society was completed.

Although the Sui Dynasty was the beginning of the parallel of law, order, style and form, the Sui law (including the imperial law and the great cause law) and its order, style and form were not completely preserved. There are complete laws and sketches in the Tang Dynasty. Although Ling, Ge and Shi have not been handed down to the world, a considerable number of lost articles can be collected from ancient books, and some fragments are also preserved in Dunhuang documents. On this basis, we can compare and analyze their contents, so as to get a glimpse of the whole code system of the Tang Dynasty. The process of compiling the code in the Tang Dynasty is shown in the above table (according to the criminal law records of the two Tang Dynasties and Yang Tingfu's On the Early Laws of the Tang Dynasty).
