Origin Story
传说中，彭祖活了八百多岁，寿星活了一千多岁。有人说彭祖比寿星差远了，也有人说彭祖有彭祖的优点，寿星有寿星的长处，各有千秋。其实，人生道路不同，成就各异，只要尽力而为，何必互相攀比呢？就如同百花齐放，各有千秋，红的似火，白的如雪，粉的似霞，黄的如金，每一种花都有其独特的美丽，各有千秋，各有特色。我们不应该只欣赏一种花，而应该欣赏所有的花，因为每一种花都有其独特的价值，都能给我们的生活增添色彩。
Legend has it that Peng Zu lived for more than 800 years, and Shou Xing lived for more than 1000 years. Some people say that Peng Zu was far behind Shou Xing, while others say that Peng Zu has Peng Zu's advantages, and Shou Xing has Shou Xing's advantages; each has its own merits. In fact, the paths of life are different, and achievements vary. As long as we do our best, why should we compare ourselves to each other? It's like a hundred flowers blooming together, each with its own unique beauty. Red like fire, white like snow, pink like clouds, yellow like gold; each flower has its unique beauty and characteristics. We shouldn't only admire one kind of flower, but all of them, because each has its unique value and can add color to our lives.
