Farmers pay public grain, which means farmers pay agricultural tax. All individuals or units engaged in agricultural production and earning agricultural income need to pay taxes. Since 2006, China has abolished the requirement that farmers pay agricultural taxes. This measure is one of the measures to solve the problems of agriculture, countryside and farmers, which reduces the burden on farmers, embodies the policy of promoting and ensuring agricultural development with industrial development in China, and is also an important embodiment of China's reform, opening up and transformation in the new period. During the War of Resistance against Japanese Aggression period, the Shaanxi-Gansu-Ningxia Border Region successfully applied China's United front theory to the collection of public grain to save the country, and properly handled the rural class relations, which not only ensured the grain supply, but also helped farmers develop production. At the same time, the border administration has also formed a relatively complete food work system in practice. This move mobilized the enthusiasm of the broad masses of people to support the war of resistance, made necessary preparations for the victory of the war of resistance, and also marked the maturity of our party's United front work.

Public grain should start with Shang Yang's political reform, which was during the Warring States Period in China. As a legalist, Shang Yang, with the support of others, reformed in the State of Qin. The main content is to formulate policies and regulations around the agricultural war and then resolutely implement them. In addition to serving in the army, the vast majority of people in Qin state have to turn over grain to the state, and the harvest can also be awarded. Later, Han was also affected by this. It is often grain that is taxed on farmers, which has been used by later generations until the state abolished the system of handing over public grain not long ago.

* * * Before the founding of the People's Republic, the armed struggle was to levy public grain to fight. Simply put, it is to distribute rations to every grain grower. But unlike the previous generation, the revolutionaries initiated the agrarian revolution, deprived landlords of their privileges and distributed land to a wider range of poor people. After the founding of People's Republic of China (PRC), the system of grain depots was established, and public grain continued to be collected.
