(1) Drinking realgar wine, it is said that after Qu Yuan threw himself into the river, people threw zongzi and salted eggs into the river to feed the ichthyosaurs in order to prevent Qu Yuan from being injured by the ichthyosaurs in the river. An old doctor brought an altar of realgar wine and poured it into the river, saying that he wanted medicine to stun ichthyosaurs. After a while, a dizzy dragon really floated on the water, with a skirt on its beard. People pulled the dragon ashore, skinned it, pulled out its tendons and relieved their hatred. Then wrap the dragon tendon around the child's wrist and neck and wipe it with realgar wine. Let those poisonous snakes and pests dare not hurt a pure-hearted child like Qu Yuan. (2) Acorus calamus wine. Drinking calamus wine is a traditional custom of Dragon Boat Festival. Chen Zeng, a scholar in the Southern Song Dynasty, wrote a poem "The calamus overflows at the beginning of May every year". Su Shi's poem "Three-year Dragon Boat Festival Sticking to Yuan You: Empress Dowager Pavilion II" reads: "Longevity calamus wine, thousands of gold amber cups." Ouyang Xiu's poem "Fisherman's Passion" said, "When orchids bathe, calamus wine is beautiful." In Song Dynasty, Dragon Boat Festival was called Magnolia Festival. Janice's poem "Qinyuanchun" says: "Sunflowers and pomegranate flowers are noisy, and calamus wine is beautiful. They have all become guests and compete like home. " During the Dragon Boat Festival, Mei, a poet in the Song Dynasty, preferred not to drink wine without calamus. He wrote in the poem "Afternoon Day": "If you have wine, you will not get sick, and there will be no calamus roots." Get calamus wine in the evening, and write down "Get calamus at midnight": "It is better not to get calamus at dusk. How can you avoid custom, three-bow pot? " "If you need the poem" Run the Week in Five Days ",say," Why not fill the calamus wine and quickly break the golden banana? "Qu You, a poet in the Ming Dynasty, wrote a poem" Acorus calamus wine ":"The calamus is picked in Duanyang, and the wine is very fragrant. Wish you a happy birthday with corn cane pith, why not indulge in drunkenness! "Li Shizhen once pointed out in Compendium of Materia Medica that" Acorus calamus wine can cure thirty-six wind and twelve arthralgia, dredge blood vessels, cure bone flaccidity, and be effective if taken for a long time ". Why do people drink calamus wine on Dragon Boat Festival? It turns out that May was regarded as an "evil month" in ancient times. The Chronicle of Jingchu's Age records that "May is commonly known as bad month, and there are many taboos". Since it is an "evil month", we must seek ways to eliminate disasters and eliminate drugs. In the Song Dynasty, Acorus calamus, a valuable medicinal material, was regarded as a "thing to ward off evil spirits" by Taoism, so drinking Acorus calamus wine was very popular in the Ming and Qing Dynasties to ward off evil spirits. There are records about calamus wine in Deliberately Written by Liu Ruoyu in Ming Dynasty and Victory of Emperor Jingdi in Qing Dynasty written by Pan Rongbi. From this perspective, drinking calamus wine on Dragon Boat Festival is to ward off evil spirits and drive away poison. Long-term use can dispel diseases, strengthen the body and prolong life. According to the literature, there was an example of drinking "Acorus calamus wine" during the reign of Guangqi in the Tang Dynasty (885-888). Yin wrote in a poem in the Tang Dynasty: "Youth Festival is more affectionate, but when you get old, you will know that you will be emotional, which will not help you to follow the customs, but will pray for wine." Later, it gradually spread widely among the people. It has been recorded in all previous dynasties, such as The Secret of Outer Taiwan in the Tang Dynasty, Qian Jin Fang in the Song Dynasty, Taiping Sheng Huifang, Yuan Man Lei Chao, Ming Dynasty's Compendium of Materia Medica, Qing Dynasty's Puji Fang and Qing Man Lei Chao. Acorus calamus wine is a traditional seasonal drink in China, and emperors in past dynasties also listed it as a seasonal fragrant mash for imperial meals. In the Ming Dynasty, Liu Ruoyu recorded in the History of the Forbidden City: "At noon on the fifth day, I drank cinnabar, realgar and calamus wine and ate zongzi. In Qing Dynasty, Gu Tieqing also recorded in Jia Qinglu: "Studying realgar powder, cutting the roots of Acorus calamus and drinking with wine is called Acorus calamus realgar wine". Because realgar is poisonous, people no longer use realgar to make wine, but drink calamus wine.
