The old lady was a kind person. Since she and her husband couldn't finish a whole table of meals by themselves, she gave some sweet potato to the child to eat.
"Delicious, mom, I want to eat sweet potato too," the child's mouth is the most honest, feeling that the old lady's sweet potatoes were tastier than any he had before.
Nowadays, kids' tastes are ruined by snacks, it's rare for a picky child to choose coarse grains over junk food. It's nothing fancy but the young mother took it to heart.
But where to buy sweet potatoes in this season? The young mother casually asked the old lady, took note of it, and the next day went to the Agricultural Specialty Store mentioned by the old lady, also picking up several pounds of sweet potatoes. While buying them, the young mother saw the Agricultural Science Academy's recommended green non-polluting products, which prompted her to also buy a few pounds of sweet potato flour and sweet potato leaves in cans to take home.
