Origin Story
从前，有个名叫小石的年轻画家，他勤奋好学，画技日益精湛。一次，他怀着激动的心情参加了省级美术展览会。展览会上，名家大师的作品琳琅满目，技法精湛，令人叹为观止。小石的作品虽然也有一定的水平，但在这些名家大师的作品面前，却显得相形失色，黯然失色。小石并没有气馁，他虚心向各位大师学习，不断改进自己的绘画技法。经过几年的努力，他的作品终于在全国美术展览会上获得了大奖，这时的他，再也不是当初那个相形失色的小石了。
Once upon a time, there was a young painter named Xiaoshi, who was diligent and studious, and his painting skills became increasingly refined. Once, he participated in a provincial art exhibition with excitement. At the exhibition, the works of famous masters were dazzling, with exquisite techniques that were breathtaking. Although Xiaoshi's works also had a certain level, they paled in comparison to those of these famous masters. Xiaoshi was not discouraged, he humbly learned from the masters, constantly improving his painting techniques. After years of hard work, his works finally won a grand prize at the national art exhibition. At this time, he was no longer the insignificant Xiaoshi of the past.
