- In a secluded corner, there is a closed world where a person lives, and his name is Shang. This world is his everything, and he has no other choice. He is isolated within four high walls, unable to see windows or the sky. Living in this environment, he is content because he does not know the outside world.
- From old books, from the yellowed pages inside, he read that there was a civilization beyond this world. He read about how people built cities, created technology, and realized dreams through wisdom and effort. These books are his hope and his pain because he knows that all of this is beyond his reach.
- He does not know why he lives in such an environment, nor does he know if he can leave this world surrounded by high walls. He only knows the pain in his heart because he cannot fulfill his longing for civilization. His heart is like a barren land, longing for the nourishment of life but never receiving it.
- He lives like this, every day wavering between despair and hope. He is in pain, confused, and longing, but he cannot change his fate. However, he always maintains a resilient faith, the belief that he will eventually get out, which serves as the pillar of his life and keeps him from being too lost in life.
- He knows that only through persistence can he find a way out. He knows that only through longing can he illuminate the darkness in his heart. He knows that although reality is cruel, his heart can still embrace hope. Because, no matter where he is, his heart always faces civilization.
- This is Shang, a person enclosed within four high walls, a person filled with longing but unable to fulfill it. His story is about struggle, hope, pain, and courage. He is a reflection of all of us, and his story is the story of all those who pursue a better world and a better life.
