Extended data:
Wowotou used to be the staple food of the poor in Beijing. It 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 (called Wowoer in Beijing), and because it is the same staple food as steamed bread, Beijingers call this food Wowotou.
In the past, when describing a person's tragic fate, he often said, "He has been hungry and tired all his life, eating steamed buns." 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.
