1, Wowotou, a common pasta in northern China. Natural green whole grains are used as the main raw materials, with high cellulose content, which can stimulate gastrointestinal peristalsis and prevent constipation, enteritis and intestinal cancer. The corn oil contained in it can reduce serum cholesterol and prevent hypertension and coronary heart disease.

2. Wowotou is a green, nutritious and healthy food nowadays. Coarse grains are widely loved by consumers because they are good for health.

Wowotou is made of corn flour or mixed noodles. The big one is half a catty, and the small one is two or three. Wowotou is conical in shape, with a small top and a large bottom and a hollow center. In order to facilitate steaming, there is a hole at the bottom, and because it is the same staple food as steamed bread, it is called Wowotou. Two-part allegorical saying "Wowotou turns over-revealing big eyes" means that when Wowotou turns over, a big round eye (that is, a round hole) appears in the sky, which is used to describe showing off, but it is ugly, often with contempt and irony.
