Origin Story
老张退休后回到阔别三十年的家乡，村口的老树依然挺拔，但村舍早已换了模样，高楼林立，柏油路取代了泥泞小路。他看着眼前的一切，心中涌起一股强烈的隔世之感。曾经的伙伴如今都已满头白发，谈话间，往事如烟，他们回忆着儿时的趣事，一起畅谈着对未来的展望，但时间的流逝却让他们感受到了岁月的无情，一切似乎都变了，只有那份深厚的友谊依旧。老张感叹道，家乡变化如此之大，如同隔了一个时代。
After retiring, Lao Zhang returned to his hometown, which he hadn't seen in thirty years. The old tree at the entrance of the village was still standing tall, but the houses had long been replaced. High-rise buildings stood tall, and asphalt roads replaced the muddy paths. As he looked at everything before him, a strong feeling came over him, as if he were in another time. His former friends were now all gray-haired. As they talked, past events seemed like smoke. They reminisced about funny things from their childhood and discussed their future plans, but the passage of time made them feel the ruthlessness of the years. Everything seemed to have changed, but their deep friendship remained. Lao Zhang sighed and said that his hometown had changed so much, as if an era had passed.
