1, Geng: The original meaning of the word "Geng" has not been seen in the literature, which is quite controversial. As early as in Oracle Bone Inscriptions, "Geng" has been used as the name of the seventh day of work. The ancients matched stems and branches with the five elements, five sides, five flavors and five permanents, so Geng was given the meaning of "gold" and "righteousness".

The etymology of Geng:
The word "Geng" was first seen in Shang Dynasty, and its pictographic meaning is very heavy. Later, Oracle Bone Inscriptions made a top fork, and it hasn't changed much since then, until Xiao Zhuan in Qin Dynasty. The small seal script of Shuowen divides the middle part into left and right hand shapes. Qin Li changed the left and right parts to be asymmetrical, the right side flattened and the left side remained unchanged.
When it developed to the Eastern Han Dynasty, the two oblique pens in the upper part became horizontal pens, adding a little more. Finally, regular script integrates the top and left lines of the word "Gan" into a "wide" prefix, and the vertical pen in the middle is divided into a "person", which is the word "Geng" seen today.
