What are the quick words?

Kuai, a first-class Chinese character, pronounced kuài, was first seen in Biography (in Shuo Wen Jie Zi [1]), which originally meant happiness and happiness, that is, the so-called "Xi Ye" in Shuo Wen Jie Zi, and extended to be quick, straightforward and ready.

Come on, pictophonetic characters. There is no word "fast" in Oracle Bone Inscriptions and Jin Wenzhong. It is a word created by pictophonetic characters only in Qin Zhuan (Xiao Zhuan in Shuo Wen Jie Zi), with "(Xin)" as the symbol and "Zi" as the symbol. From Xiao Zhuan (Figure F) to (Figure G) and regular script (Figure H), the shape of the word "Kuai" has not changed much, and the evolution is easy to see. Its original meaning is "happy", "happy" and "happiness", all of which are strong feelings from the heart, so it is expressed by "standing by the heart".

Every day brings happiness, I feel happy, I am naturally cheerful, I do things neatly, I am agile, and I am proud of the spring breeze, so I later used "fast" to mean "fast", "agile", "happy" and "happy", as opposed to "slow". It also means "sharp" and "bold", but these are all post-uprisings.
