Yi and Yi are interchangeable words.
"Yi" is a knowing word. The upper part of the word is the word "water" written horizontally, and the lower part is the "dish" of the vessel. The original meaning is that the water in the vessel is too full and flows out.
Later, people added a pictophonetic word "Yi" to "Yi" and created a pictophonetic word "Yi" to replace the original. However, the original "Yi" was not abandoned, but the meaning of "Yi" was given to "Yi", and other meanings continued to be retained.
