Origin Story
老村长李大爷一生都过着质朴无华的生活。他住在村头一间小小的土坯房里，房前屋后种满了蔬菜瓜果。他每天起早贪黑地劳作，辛勤耕耘着自己的土地。他从不追求荣华富贵，也不羡慕城里人的花花世界。他总是穿着补丁摞补丁的衣裳，脚上踏着磨损严重的草鞋，但他脸上总是带着满足的笑容。他乐于助人，总是热心地帮助村里的乡亲们解决各种困难。他从不计较个人得失，他的质朴无华，他的善良正直，赢得了所有人的尊重和爱戴。

Every day, he worked from dawn till dusk, diligently cultivating his land. He never pursued wealth and glory, nor did he envy the glamorous world of city people. He always wore clothes with patches upon patches, and worn-out straw sandals on his feet, but he always had a satisfied smile on his face. He was kind and always enthusiastically helped the villagers solve various difficulties. He never cared about personal gains and losses, his simplicity and honesty won the respect and love of everyone.
