This is a village in the 1970s, Guangyi Village, Yunze Township. The village is approximately five kilometers in radius, and there are 13 villager groups of 135 households with 1201 people. In May, the setting sun shone obliquely over the houses, bridges, and rivers in the village, as if covered with a soft layer of gold. A straight road runs through from a distance, and an eight-meter-wide bungalow stands prominently on the roadside. This is the Guangyi Village Cooperative. The door is a row of glass cabinets, displaying stationery, paper and other supplies. At the left corner of the cabinet, there are 70s signature snacks-ear ears, 2 knits per pound, no food stamps. This is the favorite of Guangyi Village children. In many cases, children between the ages of 3 and 15 can often be seen wandering in front of the counter of the cooperative, staring straight at the jar full of snacks.
