The copywriter is incompetent, let's talk about it later. I have no trap, no lower limit, no moral integrity, and the ending is all clouds, so people who read this article should not even think about seeing the ending. (Warm reminder: Please bring your own lightning rod. The author is not responsible if the outside is scorched and the inside is tender!) This is the first time the author writes an article, and his writing style is childish. Please bear with me!
