Chen (pinyin: chén) is a first-class standard Chinese character. This word was first seen in Oracle Bone Inscriptions in Shang Dynasty, and its ancient glyph looks like an upright eye. When a person bows his head, his eyes are in an upright position, and the glyph means bowing. Originally meant slaves. Because the relationship between a minister and a king is like the relationship between a slave and a master, and a slave refers to an official. In ancient times, I was also an official who claimed to face the monarch.

The finger word "Chen" first appeared in Oracle Bone Inscriptions in Shang Dynasty, and its shape was mostly like an erect eye. The original meaning of "minister" refers to slaves. When slaves serve their masters, they are generally obedient and dare not look at their masters, so they use erect eyes to refer to slaves. Most of the "I" in Oracle Bone Inscriptions have no eyes. In the bronze inscription stage, a small eye was added in the middle.

There are also some cross-eye glyphs, which may be used by officials in charge of supervision. Whether I write backwards or backwards means the same thing. The Western Zhou Dynasty inherited the structure and style of Shang Dynasty, but the horizontal writing disappeared.

During the Warring States period, hieroglyphics were weakened and lines were strengthened. Most of them scribbled down the official meaning. The eye was pierced, straight, and the eye was missing about a quarter. Round eyes have become triangular sharp eyes, and eyes have become long and narrow cylinders, which are so complicated that they have lost their image. Only the stone carvings in Yishan are dignified and square, with decent pictographs and official meanings, and are accepted as the standard by Shuowen Jiezi.

So based on this form, it developed into official script and regular script.
