Origin Story
很久以前，在一个偏僻的小山村里，住着一位名叫老张的老农。他一辈子都耕种着祖祖辈辈留下的那片土地，对那片土地有着深厚的感情。他见证了村庄的兴衰，也经历了时代的变迁。从他年轻的时候，村庄还是一片欣欣向荣的景象，家家户户都过着安居乐业的生活，孩子们在田野里追逐嬉戏，大人们则辛勤地劳作，一片祥和的景象。然而，随着时间的推移，一切都发生了变化。战争的爆发，让村庄遭受了巨大的破坏，许多房屋被摧毁，田地被荒废。许多村民被迫逃离家园，寻找新的生活。老张也亲眼目睹了这一切，他年迈的双眼充满了悲伤和无奈。战争结束后，村庄开始重建，但已经不再是昔日的样子了。新的建筑拔地而起，新的道路蜿蜒伸向远方。老张看着这些变化，心中百感交集，感慨万千。尽管如此，他依然热爱着这片土地，热爱着这个他生活了一辈子的村庄。他继续耕种着自己的土地，用他那粗糙的手，守护着这片曾经饱经沧桑的土地。
Long ago, in a remote mountain village, lived an old farmer named Lao Zhang. He spent his entire life cultivating the land passed down from generations, holding a deep affection for it. He witnessed the village's rise and fall, and experienced the changes of time. When he was young, the village was a thriving place, each family living peacefully and prosperously. Children chased and played in the fields while adults toiled diligently—a scene of serenity. However, as time went on, everything changed. The outbreak of war brought immense destruction to the village, destroying many houses and leaving fields barren. Many villagers were forced to flee their homes, seeking new lives. Lao Zhang witnessed all this firsthand; his aged eyes filled with sadness and helplessness. After the war, the village began to rebuild, but it was no longer the same. New buildings rose, and new roads wound their way into the distance. Lao Zhang watched these transformations, his heart filled with mixed emotions and profound reflection. Despite this, he still loved this land, this village where he had lived his entire life. He continued to cultivate his land, protecting this once war-torn land with his rough hands.
