Five-year-old Yaya can freely travel between ancient times and modern times relying on the shabby purse left by her mother. Starting from picking up half a braised egg in the garbage, to discovering that wild vegetables are worth gold in modern times. From picking up to exchanging, from survival to business. Carrying a small basket on her back, she travels between the ancient and modern worlds, from a braised egg to a warehouse full of grain, from the brink of despair to the smoke curling from the kitchen. The village is still the same village, but life is getting better day by day.
