Duke Liu and the Tofu
Did you know that tofu, or soybean cake was invented by a southern Duke Liu of China? Instead of fussing about inheritance and fighting for power, he spent most of his time in agriculture and try to increase the yield of crops for the people in his fiefdom. The tofu was one of the first processed food of China that allows protein to be widely available for consumption on top of the rice which is mostly carbohydrate. Now everyone remembers tofu, who remembers the emperor?
