Which is better, climbing grain or piling grain?

The food in the stack is good. Cereals dried on the ground by traditional storage methods are usually called "ground cereals" by farmers. Compared with the "stacked grain" that can be stored in the grain depot, mildew will occur due to poor ventilation, and it is easy to lead to regional bad grain because of the difficulty in selling grain. Farmers who "pile up grain" are more inclined to sell grain after the spring festival and before the spring ploughing.
