What are the narrative threads of The Dumb Bean

What are the narrative clues in Dumb Beans: Cornucopia is a delicious childhood food. I remember my favorite childhood chasing after the street popcorn artisan, they shoulder a cannonball-like tool, support and then light a fire, a handful of soybean or corn beans into it, he shook the popping bucket, when the time is almost the same, "bang" sound, he twisted the switch, the inside of the soybean ripe, and crispy, and corn beans into corn flower, snow white and fragrant, it's all like a magic man, the corn flower. The cornflakes, snow white and fragrant, all this is like a magician's artisanal operation.
