A round face simply refers to a round face. It is not as wide as a pie face, but rather small, hence the term "small round face". The facial features are not concentrated, flat, and lack a sense of three-dimensionality. . To be precise, a pie face is a wide square face, but the bones hold up the flesh and expand it, so the shape is not that obvious. It is actually easy to distinguish between round faces and flat face faces. Just imagine the difference between Xinjiang flatbreads and steamed buns and steamed buns.
