A large number of millet silks were accumulated in the treasury of the Sui Dynasty.
Many granaries were built in various places in the Sui Dynasty, among which Luoxingcang, Changcang, Liyang Cang and Guangtong Cang are famous.
Stored grain exceeds one million stones.
In Zhenguan 1 1 year of the Tang Dynasty, Ma Zhou, the supervisor of the army, said to Li Shimin, Emperor Taizong: "The Sui family is responsible for storing Luokou; Xijing national treasury, also used by the state, has not been used up so far.
"The Sui Dynasty has been dead for 20 years, and Emperor Wendi of Sui Dynasty has been dead for 33 years. In the past 55 years, the grain fabrics left over from the Sui Dynasty have not been used up.
1969, a Sui granary was discovered in Luoyang, including the Jiacang site.
Covering an area of more than 450,000 square meters, there are 259 grain pits.
There is also a grain cellar with 500,000 Jin of carbonized millet.
This shows the prosperity of the Sui Dynasty.
When Emperor Wendi first ascended the throne, the national population was 4 million, and when Yang Di ascended the throne, it had reached 8.9 million. For a family of six, the national population is not less than 50 million, which was only achieved during the reign of Emperor Xuanzong of the Tang Dynasty.
Until the death of Emperor Taizong, Tang Gaozong succeeded to the throne, accounting for 3.8 million households.
During the reign of Emperor Xuanzong of the Tang Dynasty, there were 7.6 million households, 4 1 10,000 people.
Cultivated land19.44 million hectares in the ninth year of sui dynasty, and 55.85 million hectares in the middle of the great cause.
In the fourteenth year of Tang Tianbao, the land has been reclaimed14.3 million hectares.
When Yang Di ascended the throne, there were 8.9 million households, while Emperor Taizong did not have 3.8 million households until his death.
It can be seen that the Sui Dynasty was the richest dynasty in economy, and the Tang Dynasty was precisely the dynasty with the strongest military, the closest ethnic relations and the most frequent foreign exchanges in the history of China.
Economically, the Tang Dynasty was far inferior to the Sui Dynasty.
I hope my answer can help you, and I hope it will be adopted.
