Origin Story
很久以前，在一个古老的村庄里，住着一位德高望重的老人。他常常告诉村民们，万物都有其生生不息的规律，就像春天万物复苏，秋天果实累累，然后进入冬天沉寂，再到春天重新开始。他解释道，这就像一个循环，生生不息，没有终点。他举例说明，河水源源不断地流淌，山上的树木不断生长，即使枯萎了也会留下种子，来年春天继续发芽。他还说，人们的生命也是如此，一代又一代地延续下去，生生不息。
Long ago, in an ancient village, there lived a respected elder. He often told the villagers that all things have their own cycle of life, death, and rebirth, like the spring when everything comes alive, the autumn with its abundant fruits, followed by the quiet winter and the renewed beginning of spring. He explained that this is like a cycle, continuously moving, without end. He gave examples such as the river flowing endlessly, the trees on the mountain continuously growing, even when withered they leave seeds to sprout again next spring. He also said that people's lives are the same, generation after generation, continuing endlessly.
