Du Baobao is contradictory by nature and is quite extreme in life. To paraphrase the great Du Ma's famous saying: "Ah, you are the ironclad proof that I was hungry and cold, with no clothes on my body, and no food to eat." The overall explanation is that Du Baobao did not do a good job in keeping warm during pregnancy, and her plump belly caught cold. As a result, when she grew up, Du Baobao was not enthusiastic about this warm world where even the Arctic glaciers melted.
