One, in a secluded corner, there is a closed world where a person named Shang lives. This world is his everything, besides which he has no other choices. He is isolated within four high walls, unable to see windows or the sky. He lives in such an environment, content because he knows nothing of the outside world.
Two, from old books, from the yellowed pages within, he read that there is a civilization beyond this world. He read about how people build cities, create technology, and achieve dreams through wisdom and effort. These books are his hope, but also his pain, because he knows that all of this is beyond his reach.
Three, he doesn't know why he lives in such an environment, nor does he know if he can escape this world enclosed by high walls. He only knows the pain in his heart, caused by his unfulfilled yearning for civilization. His heart is like a barren land, longing for the nourishment of life, but never receiving it.
Four, he lives like this, every day, oscillating between despair and hope. He is in pain, confused, and yearning, but he cannot change his fate. However, he always maintains a resilient belief, a belief that he will eventually be able to leave. This belief forms the pillar of his life and prevents him from being completely lost.
Five, he knows that only through persistence can he find a way out. He knows that only through yearning can he illuminate the darkness within his heart. He knows that despite the cruelty of reality, his heart can still embrace hope. Because no matter where he is, his heart will always be directed towards civilization.
Six, this is Shang, a person enclosed within four high walls, someone filled with yearning but unable to fulfill it. His story is about struggle, hope, pain, and courage. He is a reflection of all of us, his story is the story of everyone who pursues a better world and a better life.
