The scene of baking sweet potatoes in the field in the 1981s is:

As long as it comes to autumn and winter, I will bake sweet potatoes myself with my friends, dig a hole in the ground, find some dry branches to heat the pit, and when the branches are almost burned, it will take almost half an hour. Throw the prepared sweet potato under the fire, cover it with a layer of soil, wait for almost half an hour, and the sweet potato will come out. Pull it out with a stick. The appearance color of the sweet potato is dark and the taste is absolutely good. When the skin of the sweet potato is torn off, the flesh of Huang Chengcheng will be like honey, and even a piece of sugar can be pulled out, and then it will be put into the mouth, sweet and delicious, and some sweet potatoes will be oily.
