Origin Story
话说唐朝有个诗人叫李白，他一生豪放不羁，尤其爱酒。有一次，他和几个朋友在山间畅游，景色宜人，诗兴大发，于是他们就在山涧边支起酒棚，开怀畅饮。他们一边吟诗作赋，一边把酒言欢，好不快活。酒过三巡，李白更是兴高采烈，挥毫泼墨，写下了一首首千古流传的佳作。酒足饭饱之后，他们意犹未尽，继续游玩，直到夕阳西下才依依不舍地告别。这次开怀畅饮，不仅让李白创作灵感迸发，更让他与朋友们增进了友谊，留下了许多美好的回忆。
It is said that during the Tang Dynasty, there was a poet named Li Bai, who was unrestrained and free-spirited throughout his life, and especially loved wine. Once, he and a few friends went on a hike in the mountains. The scenery was beautiful, and his poetic inspiration was stirred. So they set up a wine shed by a mountain stream and drank heartily. They recited poetry and enjoyed themselves immensely. After a few rounds of drinking, Li Bai became even more elated, and wrote many timeless masterpieces. After they had their fill of food and drink, they continued their outing until sunset, reluctantly bidding farewell. This hearty drinking not only sparked Li Bai's creative inspiration, but also deepened his friendship with his friends, leaving many fond memories.
