In fact, the baked wheat cake sold in Wu Dalang is not baked wheat cake, but solid steamed bread. "The Water Margin" wrote that before Pan Jinlian hooked up with Ximen Qing, Wu Dalang got up early every day to stir up a load of cooked biscuits and sell them. Before leaving home, Song Wu once said to his brother Wu Dalang: You should stay outside and go home early; Originally, I made ten cages for making cakes, but I only need to make five cages in the future. The "fan cage" mentioned here is the steamer. Thus, the baked wheat cake sold in Wu Dalang is steamed, so it is definitely not baked wheat cake, but steamed bread.
