Although the grain tickets are good, they have significant limitations.
For example, within Qingming, the attraction of grain isn't very high. Not long ago, several million catties of grain rotted by accident. This was not intentional; the speed of building warehouses couldn't keep up with the speed of producing grain.
To consume the grain, the guinea pigs bred by Old Daoist Chu He have reached over a hundred million. Several large breeding farms have been established. At this time, with the increased production of Qingming concrete, the Old Daoist luxuriously built breeding farms with reinforced concrete. Each farm has ten floors, with countless guinea pigs housed on each floor.
Due to the cramped and crowded conditions, each guinea pig is quite unhappy, so eating became their only joy in life, thus they grew fast and fat. So the Old Daoist replicated this by building several more similar farms.
