Origin Story
老张被冤枉入狱，在阴暗潮湿的牢房里，度日如年，每一天都仿佛经历了无尽的煎熬。他思念妻子儿女，思念自由的生活，这种思念像藤蔓一样缠绕着他的心，让他无法呼吸。牢房里空荡荡的，只有他一个人的呼吸声和滴答作响的时钟，这声音如同催命符，每一下都敲击着他的神经，让他更加痛苦。他开始回忆从前，那些快乐的时光仿佛是一场遥远的梦，而现在，他却身处炼狱之中。他不知道什么时候才能重获自由，每天都活在恐惧和绝望之中，日子一天天过去，却感觉像是一年一年地流逝，他仿佛在时间的泥沼里挣扎，寸步难行。
Lao Zhang was wrongly imprisoned, and in the dark and damp prison cell, each day was like a year, and every day was as if he experienced endless suffering. He missed his wife and children, and the freedom of life; this longing was like a vine entwining his heart, making him unable to breathe. The prison cell was empty, and only his breath and the ticking clock were heard. This sound was like a death knell, each strike hitting his nerves, causing him more pain. He began to recall the past, the happy times seemed like a distant dream, but now he was in purgatory. He did not know when he could regain his freedom, living in fear and despair every day, the days passing one by one, but feeling like years passing, as if he were struggling in the quagmire of time, unable to move an inch.
