True or false, false or true. What is the whole poem?

Fake is true, really false, and there is no omission. It comes from A Dream of Red Mansions written by Cao Xueqin in Qing Dynasty.

The meaning is false. When it's real, it's really fake. If there is nothing, there is nothing.

A Dream of Red Mansions: The First Time: Yin Shi took it. It turned out to be a bright jade with clear handwriting, engraved with the words "psychic Baoyu" and followed by a few lines of fine print. Just as he was about to take a closer look, the monk said that he had reached the dreamland, so he snatched it from him and passed through a big stone archway with the Taoist priest, on which were written four big characters, "Too Dreamland". There is another couplet on both sides, which reads:

False is true, true is false, and inaction is everywhere.

Introduction:

The core of A Dream of Red Mansions is "taking the fake seriously, being true and false, and doing everything everywhere". Experts believe that this philosophical poem is the crowning touch of A Dream of Red Mansions. Philosophical sentences are the essence of Sun Tzu's Art of War.

In the first time of the whole book, I pointed out this sentence to tell you that this book is not realistic, but an illusory story, which is purely fiction, and this is also the original intention of this book, and the vast scholars and ethereal real people are the introduction, which undoubtedly implies that readers should never take it seriously.

Although you can't take your mind seriously, it's not useless nonsense. This sentence tells everyone that you don't have to care too much about everything. Seriously, you lose. There are some things you don't need to take seriously. What you take for granted is worthless in the eyes of others, and what is priceless in the eyes of others may be chicken ribs for you.
