Lin Wanxing opens her eyes and directly time-travels to the countryside in the late seventies. With zero family assets in her pocket, she carries a check-in system instead, acting like a mobile mystery box machine. While everyone else hoes the fields every day to earn work points, she starts from a bundle of damp firewood and a board of plastic hair ties, selling hair clips and setting up a snack stall. Her little life rolls like a snowball, growing rounder and fuller. Team leader Lu Yan is cold on the outside but warm on the heart. The day the pagoda tree flowers fall, he finally passes out the words kept in his heart. The stall will turn into a shop, and the shop will turn into a tailoring store. Later comes the college entrance examination, and diving into business. But all of this starts from that window that was still glowing that winter.
