The Grain Reserve Bureau is the administrative agency responsible for the national reserve materials. The Grain Reserve Bureau is the unit that ensures the safety, sufficiency and effectiveness of the national reserve materials. It is responsible for formulating the management system and standards of the reserve materials, purchasing, storing, keeping and allocating the reserve materials, counting and monitoring the reserve materials, and providing data support for national decision-making. Therefore, the Grain Bureau is the administrative agency responsible for the national reserve materials. Working in the Grain and Material Reserve Bureau is relatively low in intensity, because it mainly involves the storage and management of materials, rather than directly participating in production and operation. However, when dealing with emergencies or special circumstances, it is necessary to strengthen the allocation and management of materials, and the work intensity will increase.
