During a blizzard disaster year, old lady Liu Yufen tearfully jumped off a cliff to save food rations for her family, but unexpectedly traveled through to a modern recycling station. She was taken in by a kind-hearted boss who provided food, lodging, and wages. Liu Yufen earned money by picking up junk and bought modern food to take back. Since then, Liu Yufen shuttled between the two realms, and her business in ancient times also became a huge hit all the way, improving her family's livelihood.
