Peace is black slang, which is usually used at the end of a sentence. It used to mean "goodbye" or "peace". For example, the meaning of "I'm leaving, guys, and going out peacefully" has now been extended, which can mean the end of a paragraph, or it can mean "take care" and "see you later". In short, it is a conclusion full of hip hop. Generally speaking, short messages or online chats are abbreviated as PCE. If you want to put on airs, it is often a love for many purposes. For example, if you want me to explain clearly, you can say "I'm leaving, goodbye, I love you"
