He lived in ancient times when vegetation grew wildly and beasts roared everywhere. There were no bronzes, jade or silk, only stone tools and animal skins. The days are not about competing for supremacy, but when you open your eyes, you have to wonder whether today's bonfire can last until night, whether the pottery can be filled with clean water, and whether the tribesmen can get a piece of oily animal meat. He learned to polish stone axes to make their blades sharper; to tan animal hides to make clothes warmer; to distinguish edible vegetation and trees, and to build stone houses that could withstand wind and rain. Hunt with the tribe, share the prey together, and resist sudden wind, rain and wild beasts together. There are no earth-shattering stories, only the steadiness of working at sunrise and the stability of resting at sunset. In this wasteland, he turned his rough life into an ordinary life with one meal, one vegetable, one house and one fire, full of fireworks.
