According to legend, in the summer of the twenty-third year of Jianwu (forty-seven years), Ma Yuan led an army to the Peach Blossom Garden. Unexpectedly, many soldiers fell ill overnight, while Ma Yuan listened to the war report in the sickroom. Suddenly, he heard the report that the people offered soup and medicine. Ma Yuan, who was suffering from the disease, drank a big bowl incredibly, only feeling fragrant and refreshing. He drank three bowls in a row, sweating all over, and miraculously stood up on his limbs. As if sweating like a pig, all three armed forces were under control, the plague was eliminated, morale was greatly boosted, and the flag was won. Some of these legends involve Liu Bei, some involve Zhuge Liang and Zhang Fei, but most of them mention Sima Cuo and Ma Yuan. Only Ma Yuan said this, which can be seen in historical records: In 280 BC, Zhao Haoqi of Qin stationed troops in the south, built a city in Nanyang, with a long Mausoleum, adjacent to the Peach Blossom Garden. The Taohuayuan County Annals compiled by Emperor Kangxi recorded Ma Yuan's recruitment of five creek men. Soldiers have discipline, and chickens and dogs are not surprised. Therefore, Ma Yuan chiseled a stone chamber to appease the people, and the people rewarded them with tea.
It is generally believed that tea smashing originated in the Central Plains, and it was handed down with the southward migration of Hakkas in the Tang and Song Dynasties. An ancient poem in Yulin Shihua describes the custom of drinking tea in Jiangnan at that time:
There are two or three thatched cottages along the road. See the customers patting their horses for tea.
Zhongyuan has a good pronunciation, but I don't know that Huaishui is the end of the world.
