Is it true that big head is a gentleman and big foot is a villain?

This is the face-to-face result of distinguishing between the rich and the poor, mental workers and manual workers in the old society, and it is the standard to distinguish between gentlemen and villains. In the past, the rich and mental workers were considered gentlemen, while the poor and manual workers were considered villains. The rich and mental workers usually have bigger heads than the poor and manual workers, while the latter have bigger feet. So this statement is correct.
