In the following days, the couple Yingbao and her husband roamed the world with their daughter, collecting various grains and crops.
The crops yielding the highest volume of grains were potatoes and a type of red-skinned sweet potato, in addition to a type of corn. The corn's stalks were sweet, and the grains, once ground into flour, could be made into thin pancakes that were incredibly sweet and delicious.
Wei Zhan highly prized this type of corn as its sweet stalks, once chopped down, could serve as excellent fodder for animals.
"We can save a lot of grain with corn as feed," said Wei Zhan. During winter, cattle and sheep need to eat, and feeding them just regular grass won't suffice. They ought to eat a combination of beans and laboratory-approved green feed.
This type of corn, once chopped and fermented with wheat bran and rice husks, could also serve as animal feed.
