In the third year of Chunhua in Song Taizong (992), the Song Dynasty began to set up permanent warehouses in Gyeonggi. After three years in Jingdezhen (1006), it has been widely set up all over the country, except in border counties. According to the population of each state, the amount of remaining contributions is 200,000 to 2 million. Every summer and autumn, food prices are cheap, and the market price rises by three or five articles. When the food price is high, the reduction shall not be lower than the capital. If you haven't harvested for more than three years, you can reload the grain, and it is easy to use new grain. After Jing, due to the surplus of grain in Changping and the lack of grain in the third division, Changping was often transferred to help make up the military expenses. In the second year of Xining (1069), the young crop method was implemented, and the young crop method was used instead of the constant liquidation method. The accumulated15 million yuan (including the money accumulated in Guanghui warehouse) is also used as young crop money, which is lent before summer and autumn every year, and will be repaid in two taxes after harvest, and promised to be divided into two parts. After seven years, the interest will be charged at half the money, while the young crops will only be paid once a year, and the price will be reduced at half. In nine years, Changping's money and goods increased to more than 37.39 million pieces. In the ninth year of Shaoxing (1 139), after the regular warehouse was rebuilt, the old method of scattered collection was restored. The main road (1 167) has accumulated 3.579 million meters of stone in Changping and Yicang roads, with a capital of 2.87.110,000 yuan, most of which are empty. For example, in Xinzhou, there are 93,000 stones in the household registration book, and the reported number is 68,000 stones, and the duplicate record is only12,900 stones. Constant liquidation has existed in name only.

In the 14th year of Dading in Jin Shizong (1 174), a continuous liquidation system was established, which increased the market price by two tenths in good years and decreased by one tenth in thrifty years. It was ordered to be implemented nationwide, but it was soon abolished. In the first year of Ming Chang in Zhang Zong (1 190), grain was stored in March according to the number of county accounts, which enabled the Criminal Division and the Road Planning Division to receive it. In the past three years, due to the frequent name change, the "Law on Reward and Punishment for Diligence and Laziness" was issued to local officials, and it was customized that those within 60 miles from the county should be located in the state warehouse, and those beyond 60 miles should not be set up. The original grain storage in March was changed to grain storage by households, with 30,000 stones for more than 20,000 households and 5,000 stones for less than 5,000 households. In the past five years, China has 5 19 warehouses and accumulated 37.86 million stone grains. In the third year of Hongwu in Ming Taizu, counties were ordered to set up reserve warehouses in the four townships (moved to the city in Yongle) to store official banknotes for relief. During the famine years, Qiu Cheng borrowed money from the people and repaid it, so it was customized for a generation instead of regular liquidation. At the end of the Ming Dynasty, long positions were set up in some border towns in Liaodong and Yansui. During the reign of Shunzhi in the Qing Dynasty, various governments, prefectures and counties set up Changping, Yihe and Shecang, and instructed Taoist priests to be responsible for compiling and reporting them to the Ministry of Housing every year; In 17 years, the method of bumper harvest was set, harvesting in spring and summer, returning in autumn and winter, and the price was fair. In case of disaster, give relief. During the reign of Kangxi, it was decided to borrow money in spring and return it in autumn, with a barrel of interest for each stone; Grain stored in Changping and Yizhi will always stay here for relief. It also stipulates the amount of food that should be stored in large, medium and small counties. Later, due to lack of money, the county official was ordered to "persuade" Changping and other grain depots. The rule of "stay in your native land forever" is often not enforced. After the mid-term, the disadvantages became more and more serious, and all localities often collected most of the money and grain, which was only nominal, and could not stabilize food prices and prepare for famine.
