What's at the bottom and next to the word?

The bottom and side of the word are: Bi, which is pronounced as the beginning and used as a radical, the same as Bi in ancient times.

"Xi" is called "walking side" or "walking bottom". Seal script is the radical of Chinese characters, and its pronunciation is Chu Dong. Commonly known as "line bottom" or "line son" for short, it actually comes from "Chu" rather than "line" or "knowledge"

In the traditional word book, it is the chuò department. "Jump" means stop and go. There are many words in this category, such as "advance" and "retreat".

Difference:

In modern Chinese, the three radicals "bi", "mi" and "bi" have different names respectively: "bi" is called "walking the side" or "walking the bottom" and "bi"

In ancient Chinese, these three radicals are closely related: "Kuai" is interpreted as "stop at first sight" in Shuowen Jiezi, which simply means "stop and go"; Mao is interpreted as a "small step" in Shuo Wen Jie Zi, which is simply a "small step".
