With the World Food Day approaching, in the central grain depot of Zhongshan Grain Reserve Management Co Ltd (ZSGR), a group of "grain keepers" try their best to safeguard "the granary of Zhongshan" by heart.

Starting from mid-June, the central grain depot has seen peak grain storage and warehousing traffic every day: large trucks with grain shuttle between warehouses, and golden rice and wheat flow along various conveyor belts. Here, a tough battle to create a robust reserve of grain is underway.
