Origin Story
很久以前，在一个偏僻的小山村里，住着一位老农。他靠种地为生，日子虽然清贫，但也算过得安稳。一日，老农在田里干活时，不慎失足跌落进河中。河水湍急，老农奋力挣扎，却怎么也爬不上岸。河水冰冷刺骨，老农感到体力渐渐不支，他知道，如果没有人来救他，他就会被湍急的河水卷走。就在这时，他看见不远处有一棵大树，树枝低垂，几乎触及水面。他鼓起最后的力气，奋力抓住树枝，终于被拉上了岸。上岸后，老农浑身湿透，瑟瑟发抖。他惊魂未定地环顾四周，发现身边并没有人，只有无情的河水依然奔流不息。这次死里逃生的经历，让老农深深地体会到，水火无情，自然的力量是不可抗拒的。从此以后，老农更加敬畏自然，小心谨慎地生活着，再也不敢轻易靠近河水或火源。
Long ago, in a remote mountain village, there lived an old farmer. He made his living by farming, and although his life was poor, it was also peaceful. One day, while working in the field, the old farmer accidentally fell into the river. The river was swift, and the old farmer struggled hard, but he couldn't climb ashore. The river water was icy cold, and the old farmer felt his strength gradually failing. He knew that if no one came to rescue him, he would be swept away by the swift river. Just then, he saw a large tree not far away, its branches low, almost touching the water. He mustered his last strength, grabbed the branches, and was finally pulled ashore. After landing, the old farmer was drenched and shivering. He looked around in shock and found that no one was around, only the merciless river flowing endlessly. This near-death experience made the old farmer deeply understand that water and fire are merciless, and the power of nature is irresistible. From then on, the old farmer was even more awestruck by nature, living cautiously and carefully, never daring to approach the river or fire source easily.
