This is the B-11 work of the Childhood illustration series, depicting the daily childhood scene in northern winter snow in old times. Several children with charcoal ash on their faces roast sweet potatoes around a simple firewood pile, with raw sweet potatoes, peanuts and corn scattered nearby. The child next to the thatched hut holds freshly baked hot food, and a naughty puppy tugs at the child's clothes. The rising heat turns into soft cloud-like patterns, full of simple fireworks, evoking warm childhood memories for the post-70s and post-80s generations.
