Think of an ancient poem, which probably means drinking water by the river, and then putting the cup in the water, whoever flows there will drink it.

Water flows out to Wang Xizhi's Preface to Lanting Collection. Qushui [1], also known as Liubei Qushui or Qushui Liu Shui, is a dietary custom in the old Shangsi Festival. Its general practice is that people sit around the curved canal and put special wine glasses (mostly lacquerware with light texture) upstream, so that they can float slowly along the tortuous water flow. Whoever floats in front of the cup will have a drink. Go back and forth like this until you have fun. Scholars have developed this custom into an elegant gathering of celebrities-whoever stops in front of the glass will write a poem, which is as interesting as "handing a parcel" or "throwing a handkerchief" of modern people. During the Wei and Jin Dynasties, literati liked to attack the ancient style, drinking and having fun all day, indulging in mountains and rivers, being indifferent to Laozi and Zhuangzi and roaming in calligraphy. This elegant drinkers' wager game, like "Chun Xue", is not only a means to punish wine, but also outstanding because it is punished as the participation of poetry, an elegant and elegant spiritual activity.

On the third day of March in the ninth year of Yonghe in the Eastern Jin Dynasty (353), more than forty people, including the great calligrapher Wang Xizhi, celebrities Xie An and Sun Chuo, gathered in Lanting, Yinshan, Zhejiang Province to write Qushui Hangshu. As the saying goes, "there is also a clear stream that stirs up turbulence, reflecting left and right, thinking that it is water." Sitting next to you, although not as prosperous as bamboo and orchestra, is enough to talk about your intimate feelings. These poems were compiled into Preface to Lanting Collection, prefaced by Wang Xizhi, which became a treasure in the history of calligraphy art in China. According to records, it was thought of "elegant things" such as Qushui, and the rest of the rhymes spread to the 1940s. Scenery such as "Sweeping Shuge" and "Liu Beige" can also be seen in the Forbidden City in Beijing and Lanting in Shaoxing, but they are all miniature landscapes carved with zigzag grooves on the stone foundation. Isn't this what Rainbow Xizhi said: "There are mountains, bamboo and trees"? There is a natural taste of "clear water turbulence, reflecting the left and right".
