Yan, Yun, Yu and Shuo all have the meaning of speaking. What is the difference?

Yu, that’s me on the right, that’s me.

What I am speaking is called language.

Say,

The right side is the redemption. When we Chinese speak, we must "be true to our words and achieve results in our deeds." This means that we should not talk empty words, but must turn what we say into reality, which is called fulfillment.

Speech, in ancient times, was when at least three people were together, chatting freely, talking freely, and talking about everything, which was called speech.

Yun, (this word existed in ancient times and is not a simplified word for cloud)

It is the word that changes the pronunciation of "曰". Said, pronounced month.

It is what people say, what the ancients said, and what poems said. The word "筭" that has been widely discussed, the word "brewing", and the word "cultivation" all have the same cloud character. Later, after more than 2,000 years of shaping, they each had different meanings.
