One way of saying it is twenty-four bridges. In the Northern Song Dynasty, Shen Kuo recorded the positions and names of the bridges in Volume III of Meng Qian's Bi Tan Bu Bi Tan.

Another way of saying it is that there is a bridge called Twenty-four Bridges, which is named after Li Dou's Record of Yangzhou Paintings in Qing Dynasty: "Twenty-four Bridges are brick bridges in Wu Jia, a red medicine bridge and a Zaixi Chuntai ... Yangzhou advocates word order, and the bridge is named after the ancient twenty-four beauties playing flute here."

Extended data:

Moonlit Night on the Twenty-four Bridges comes from a poem written by Du Mu, a poet in the Tang Dynasty, which was sent to Han Chuo, the magistrate of Yangzhou. The original text is as follows:

Any news for Han Chuo, Yangzhou magistrate? Du Mu

Castle peak is vaguely green water thousands of miles away, and the vegetation in the south of the Yangtze River has not withered in autumn. ?

Where does the Jade Man teach oral sex at Bridge 24 on a moonlit night?

This poem was written by Du Mu when he returned to Chang 'an from Huainan.

Yangzhou in the Tang Dynasty was the most prosperous metropolis in the middle and lower reaches of the Yangtze River. There are many shops, businessmen and restaurants dancing kiosks everywhere. "There are tens of thousands of scarlet lanterns shining in the air every morning and evening in every major city, and the streets nine miles and thirty paces away are full of pearls and greens, just like a fairyland." ("Taiping Guangji" Volume 273 quoted "Tang" and "bohemian" Du Mu, in such an environment, frequented brothels advocating family ties and having many affairs. Han Chuo is his colleague in this respect, so he wrote poems as a gift after returning to Chang 'an.

The first two sentences of this poem describe the scenery. The first sentence is a telephoto lens, and the lush mountains around Yangzhou in the distance are blurred, giving people a sense of confusion; The river flows eastward for a long time, giving people the feeling of brisk flow. The second sentence is to imagine that although the beauty of Jiangnan is autumn, the vegetation is not completely yellow. These two sentences are about the phenology of Yangzhou's mountains and rivers, which paves the way for the latter two sentences to ask Han Chuo what happened after he left. The focus of the last two sentences is to ask Han Chu if he played the flute and sang with a geisha and danced all night on a clear breeze and bright moon night.
