Origin Story
老张是一位著名的画家，他喜欢在夜阑人静的时候作画。一天晚上，月明星稀，老张坐在画桌前，眼前浮现出家乡美丽的田园风光。他提笔蘸墨，挥洒自如，一幅幅栩栩如生的画作跃然纸上。夜深了，窗外一片寂静，只有老张笔尖与纸张摩擦的沙沙声，以及他偶尔发出的满足的轻叹。他画到东方露出鱼肚白才停笔，看着自己创作的画作，心中充满了喜悦。这幅画，也成为了他最满意的一幅作品，它饱含了他对家乡的思念和对艺术的热爱。
Old Zhang was a renowned painter who enjoyed painting in the quiet of the night. One evening, under a clear sky with few stars, Old Zhang sat at his painting table. The beautiful pastoral scenery of his hometown appeared before his eyes. He dipped his pen into the ink and painted freely, one after another lifelike paintings appeared on the paper. Late at night, the outside world was quiet, only the rustling sound of Old Zhang's pen tip rubbing against the paper, and his occasional satisfied sighs. He didn't stop painting until the east showed a hint of dawn. Looking at the paintings he had created, his heart was filled with joy. This painting also became one of his most satisfactory works. It was full of his longing for his hometown and his love for art.
