The origin of Xia characters.

Xia, pictograph. There are two main views on the etymology of "Xia".

First of all, the word "Xia" in Oracle Bone Inscriptions is a pictographic character of a person: the head, hair, eyes, body, arms, legs and feet are all available, and the hands are spread out to show a powerful posture. The word "Xia" in bronze inscriptions is much more complicated than its Oracle Bone Inscriptions shape: a person's head and body become the traditional "page" structure; The two jagged parts on the left and right are pictograms of hands; Below is a hieroglyph with two toes pointing to the left, that is, "stop"

The word "Xia" in Biography is developed from its bronze shape, but there is only one "foot" left, and the structure of the whole word looks clearer. In the later period of official script, the word "Xia" was greatly simplified: the traditional Chinese character "Page" above was written in the shape of the word "Xia" in official script, the hands on both sides were omitted, and the foot below became "Ba". This has evolved into the word "Xia" in regular script. In terms of meaning, the original meaning of the word "Xia" is "brave China people" (here "China" refers to "Central Plains").

Secondly, the ancient form of the word "Xia" is more complicated in terms of its shape. In fact, the word "Xia" in bronze inscriptions is a human figure: there is a head above, a trunk in the middle, hands on both sides and a foot below. The word "Xia" in Biography is also a "human" shape, but it has been falsified, and the human body part is gone, but a big foot is still there.

The word "Xia" in regular script evolved from Xiao Zhuan and has lost its image. In terms of meaning, the original meaning of the word "Xia" is "people"-"people are in China" (here "China" refers to the middle reaches of the Yellow River, that is, the Central Plains), and then refers to the second season of the four seasons.
