Once upon a time, in a small mountain village, there lived an old carpenter named Zhang Laohan. Zhang Laohan was highly skilled, and the villagers would ask him for help with building houses and repairing furniture. Zhang Laohan was kind and never cared about how much he was paid, always working diligently and tirelessly for the villagers. One day, the house of a widowed old woman in the village collapsed, and the old woman, helpless and alone, had nowhere to turn for help. Upon hearing this, Zhang Laohan immediately put down his work and rushed to the old woman's aid. Seeing the old woman's miserable condition, he was deeply saddened and without a word, picked up his axe and began helping to rebuild the house. He worked continuously for three days and three nights, eating and sleeping outdoors, tirelessly working until the house was finally rebuilt. The old woman was moved to tears. Though Zhang Laohan was exhausted, he was full of joy. From then on, his story spread throughout the village, and everyone praised him as a kind, helpful, and tireless man.
