In the earliest Oracle Bone Inscriptions, the heart was like a heart organ. In ancient times, when people offered sacrifices, they used their hearts and hands to offer them to God. "Hand in hand" forms the heart-shaped outline of the word "Oracle Bone Inscriptions".

Second, the bronze age.
In the Bronze Age, bronze inscriptions prevailed. At this time, the heart added the image of the arteriovenous inlet pipeline on the basis of the bag-shaped organ, and added a small symbol representing blood inside the bag-shaped organ. The whole glyph is like a bag-shaped blood-drawing organ in the human body.

Third, during the Warring States Period:
At this time, China's economy and culture flourished, and Qin Shihuang unified the script as Xiao Zhuan. At this time, the "heart" of seal script characters basically inherited the bronze inscription.
Fourth, the Han Dynasty
Official script becomes the main font. At this time, the word "heart" is greatly deformed, and the shape of the capsule of the blood-drawing organ disappears, and the shape of the blood vessel also disappears. Because people at that time found that the heart is not only an organ for pumping blood, but also an organ for perception and has the ability of intuitive thinking.
