These posters are inspired by one idea: If you want to seek the truth of the world, first of all, you should look directly into your own heart, break the shackles of self, and look at the world from the perspective of a third party. Only in this way can you see the world more comprehensively and thoroughly, and become a person out of the cave. There is no greater sorrow than the death of the heart, the so-called senses are finite, and the finite is only the heart's feeling. When you are in a finite state, you can see neither your peers, nor the changing world, nor your true self.
