1. Wowotou, a common pasta in northern China. It uses natural green whole grains as the main raw material, which contains high fiber content and has the property of stimulating gastrointestinal motility, which can prevent and treat constipation, enteritis, intestinal cancer, etc. The corn oil contained in it can lower serum cholesterol and prevent the occurrence of high blood pressure and coronary heart disease.

2. Today’s wowotou is a green, nutritious and healthy delicacy. Because whole grains are good for health, it is widely loved by today’s consumers.

3. Wowotou is made of cornmeal or hybrid flour. The big one weighs half a catty, and the small one weighs two or three taels. The shape of the wowotou is small at the top, large at the bottom and hollow in the middle, in the shape of a cone. In order to make it easier to cook when steamed, there is a hole at the bottom, and because it is the same staple food as steamed buns, this food is called steamed buns. The proverb "Turn the wotou over - to show big eyes" means turning the wotou over so that a big round eye (i.e. a round hole) appears. It is used as a metaphor for being in the limelight and making a fool of yourself, often With contemptuous irony.
