Etymological evolution: The word E was first seen in Oracle Bone Inscriptions in Shang Dynasty, and it is a pictophonetic character. Oracle Bone Inscriptions's "E" has basically the same axe shape, but the font has begun to line up. The "e" in the inscription on the bronze inscription, at this time, the shape of the "e" began to change, the top hook changed, the axe handle bent, and the fork became diagonal.
