In the long-term disaster relief, the state formulated a series of laws and policies, which were institutionalized and passed down from generation to generation, and were improved day by day in the Qing Dynasty. Actively resist disasters and prepare for famine. Our ancient ancestors have long known that in the face of famine, concession can only lead to more heavy losses. Therefore, when the ability to resist natural disasters was not strong enough at that time, we still treated disasters with a positive attitude. Dayu, a famous water control hero in ancient China, led the people to accumulate soil and pay for it, dredge the river and divert water into the sea at the critical juncture of the catastrophic flood, which opened a chapter in the struggle against disasters of the working people in ancient China. In the later flood control of the Yellow River, people inherited and carried forward Dayu's spirit of flood control, and won disaster-resistant victories again and again. The deeds of Zhang Zi's blocking, Wang Jing's harnessing the river and Pan Jixun's attacking sand with water have all gone down in history. In the face of three disasters, namely flood, drought and locust, the working people in ancient China implemented active anti-disaster policies and effective measures, which minimized the hazards of famine and built a basic economic zone represented by Guanzhong area and Jianghuai basin. Preparing for famine is a preventive measure implemented before famine, and its main content is to store food for famine. As early as the Spring and Autumn Period and the Warring States Period, China adopted the policy of storing grain in case of famine to resist disasters. During the Warring States Period, Zang Wenzhong, a doctor of the State of Lu, suggested: "Build castles, belittle food, economize on food, and persuade points." Saving grain is effective in Lu, so Lu is "hungry but not harmful", while Wei advocates "teaching and doing its best", that is, the purpose of storing grain is achieved by developing production. This basically reflects the main measures to store food for famine prevention in ancient times, and has a positive impact on famine prevention in later historical periods. Stabilize the order in the disaster area. After the disaster, it will bring great shock to the society and easily make the social order in the disaster area chaotic. To this end, the state often takes measures to stabilize prices, severely punish thieves, exempt taxes, money and food, and strengthen the management of disaster areas. Li Kui has created a leveling method. According to the severity of the disaster, it requisitioned much-needed food for the victims. "The little hunger will be collected by the little cook, and the big hunger will be collected by the big cook. Therefore, despite the drought, the people will not be scattered. " The implementation of disasters is more common. After the disaster, the imperial edict of exempting money and grain was issued quickly, and the tax burden of the victims was exempted in the light disaster. If the disaster is serious, money and food can be exempted for several years in a row. These measures are conducive to stabilizing the social order in the disaster areas. Relief to appease the victims. Due to the lack of food in the disaster area, the victims not only ate up bark, grass roots and livestock manure. I also dug something called "Guanyin soil" to satisfy my hunger. It is not uncommon for a disaster to cause tens of thousands or hundreds of thousands of deaths in the history of our country. Therefore, it is naturally a major task to relieve the victims. In ancient China, there were several forms of relief for victims, such as work relief, porridge relief, food relief and money relief. Work for relief means work for relief, and the victims get relief by engaging in some urgent engineering work; Porridge relief is a porridge factory set up by the government or the people to help the hungry; Food relief and money relief are organized by the government to distribute food and money to disaster areas to solve urgent needs. The food needed for relief mainly comes from regular positions, social warehouses and voluntary warehouses. However, due to various reasons such as inconvenient transportation and official corruption, the disaster relief effect is not ideal. For example, although porridge relief could save a group of victims at that time, a large number of hungry people starved to death after running out of food. Organize the resumption of production. After the disaster, it will inevitably affect the process of agricultural reproduction. Farmland was destroyed, cattle and seeds were scarce, and farmers were short of food and clothing. Therefore, disaster relief measures were taken to organize and help the affected areas to resume production. In the first year of the Yuan Dynasty, it began to rain heavily in Zhao Di in the Western Han Dynasty, and the messengers gave relief to the poor and seedless eaters. In the thirteenth year of Yongyuan, "the rain in Jingzhou", "the poor people cheat to grow food" and "help the poor in Zhangye, Juyan, Shuofang and Rinan, such as the foresters who have lost their farming, help them grow grain and use the poor food." Through continuous development, the loan policy for supporting agriculture has played an important role in disaster relief work in various historical periods. Recruiting refugees to reclaim wasteland is another measure to restore production in disaster areas. The ability of ancient society to resist disasters was very low, which led to the outflow of a large number of victims and the abandonment of a large number of cultivated land. Starting from their own interests, the rulers had to carry out some farmland capital construction, improve agricultural production conditions, formulate a series of policies to encourage reclamation, and recruit refugees to farm, which objectively promoted the economic recovery and development of the disaster areas. Abstract: In ancient China, disasters were frequent and famines prevailed. In the long-term disaster relief, the state formulated a series of laws and policies, which were institutionalized and passed down from generation to generation, and were improved day by day in the Qing Dynasty. Generally speaking, the disaster relief system in ancient China mainly includes the above aspects.
