Lying and not changing the blood type

The first place is of course O children's shoes, O type people lie like a meal , but the lies are made by people immediately;

The second place B children's shoes, regardless of the three or seven twenty-one, type B will never admit that he lied;

The third place AB children's shoes, type AB rarely lie, but once they lie, it is difficult to see through;

The fourth place is the sad reminder Mr. A. Mr. A's character is that he can't learn to lie.
