Leicha is actually a kind of drink. Because "Jiaozi" (dialect, the paste formed after beating) is made by beating, it is named Leicha. Leicha has a long history and is known as "Leicha". The literature appears very early. This tea has been popular as early as the Song Dynasty. In the Song Dynasty, Naideweng's "Capital Records" and Wu Zimu's "Mengliang Lu" have records of "Leicha" and "Qibao Leicha". Unfortunately, the method of making Qibao Leicha has been lost. Yuan Wen also mentioned in "Weng Miao Xian Comments" written by Yuan Wen that "for the rest of his life in the Han Dynasty, he liked to sip Tian Tian Tian Tian tea most, and often passed one or two in his leisure time. Northerners knew that I sipped this, so they cooked it at the same rate, and the method was to use tea buds Take a cup, grind it into a basin of less fat sesame paste, and cook it according to the amount of people. The taste is very sweet and lovely... Tea was not eaten in ancient times. After the Jin Dynasty, people in Wu picked the leaves and cooked it. It was called Ming porridge, and it was known as Tiantiantian tea. It has been around since Jin Dynasty."

The history of Leicha can be verified by historical records. On the bamboo slips unearthed from the Mawangdui Han Tomb in Changsha, there are records that tea drinks made from tea, ginger, rice and other raw materials were used as court tributes. It is said that this was Leicha. In 280 BC, General Sima Cuo of the Qin Dynasty stationed troops south of the Yuanshui River and built a city in the Changmaoling area adjacent to Taoyuan. At that time, there was a popular "ancient soup" among the people, which was the ancestor of Leicha. After Qin Shihuang unified the six countries, the land of today's Taoyuan was included in Qianzhong County. In the early years of the Western Han Dynasty, Qianzhong County was renamed Wuling County, with jurisdiction over 13 counties, including today's southwest Hubei, the west of the Yuanjiang River Basin in Hunan, the east of Guiyang, Sanjiang, Longsheng and other places in Guangxi. Peach Blossom Spring is located in Linyuan County, Wuling County, and was called Wutou Village at that time. Some of the legends about Leicha involve Liu Bei, some involve Zhuge Liang and Zhang Fei, but most of them mention Ma Yuan. It is impossible to verify whether Liu Bei and Zhuge Liang have been to Wutou Village. Although Zhang Fei visited Wutou Village when he took Wuling, he did not leave any record of the plague epidemic. Only Ma Yuan's theory can be found in historical records.

The specific time when Ma Yuan arrived at Wutou Village (today's Taohuayuan) has no history, but according to historical data, it is speculated that it was between the 23rd year of Jianwu (AD 47) and the 25th year of Jianwu. In the midsummer of 49 A.D., "Taoyuan County Chronicles Fanli" (Kangxi Edition) records ③: "The horsemen sent reinforcements to conquer the Wuxi barbarians...the soldiers marched in an orderly manner, and the chickens and dogs were not alarmed." (The stone chamber dug by Ma Yuan and his soldiers was similar to the cave dwellings in northern Shaanxi. It has been well preserved after two thousand years of vicissitudes of life.) Folks offer tea as a reward for virtue, which is known as an eternal masterpiece. "Taoyuan County Chronicle" (Daoguang Edition) records: "Leicha is combined with tea, ginger, sesame, salt, and dogwood, and is mixed with yin and yang water to drink. It is called a five-flavor soup. It is said that Ma Yuan made it to avoid plague." It is said that Ma Yuan led the army. While stationed in Taohuayuan, many soldiers fell ill one after another, so local residents offered tea to cure their illnesses. Fu Bo, who was plagued by illness, drank a bowl of it doubtfully. He felt a fragrant fragrance enter his heart and spleen, and immediately had a taste in his mouth. He drank three large bowls in a row, and then he was sweating profusely, as if he had been suffering from illness for many days. Also flow away with sweat. He hurriedly asked: "What kind of magical thing is it?" An old woman replied: "This is the secret recipe of Wuwei Tang passed down by the gods." So, Ma Fubo hurriedly ordered the three armies to take it. All diseases in the army were eliminated, morale was greatly boosted, and the flag was raised to conquer the barbarians. There are historical relics and monumental landscape names such as Ma Shi (Chamber), Fubo Cave, Mawang Temple, and Mawang Creek in Peach Blossom Spring as evidence that the origin of Leicha has been around for a long time.
