One of the ancient tea areas in the country, the stone tea is a wonderful flower among the varieties. Some texts are recorded. In the Han Dynasty, Yang Xiong wrote "The Dialect", the Tang Dynasty Lu Yu's "Tea Classics", the Northern Song Dynasty Music History "Tai Ping Yu Yu Ji Jiangnan Road", the Ming Dynasty "Yu Ji", the Qing Dynasty "continued the book", "Guizhou Tongzhi" and modern tea The works of St. Wu Jue Nong and other historical books and Fang Zhi have recorded and described the historical origin and development of Shijie tea from different aspects. There are three more allusions about "Shizhe Moss Tea": First, Yufeng "Tianzi Tengcha" The unique wild vine tea of ​​Foding Mountain in Shiqian County has been traced to the traces of the history of the tea pharmacopoeia, and the tea saint Lu Yu is in his first section. In the Tea Classic, it is classified into the vine tea of ​​the new shoot traits. The Emperor Guangxu of the Qing Dynasty named it "Tianzi Tengcha". The earliest collection of poetry in China, "The Book of Songs", is called the ancient tea. It is the tea kingdom. The gems, the wonderful efficacy of tea, are mainly distributed on the top of Foshan Mountain in Shijie, Guizhou. According to legend, during the reign of Emperor Guangxu in the Qing Dynasty, a gentleman named Chen Zihe served as the teacher of Emperor Guangxu in the Imperial Palace. At that time, Emperor Guangxu’s body was weak, his appetite was weak, his face was pale, his voice was hoarse, his face often had dark spots and acne. . The Emperor Guangxu is extremely afraid of taking medicine, and suffering from this disease makes him very annoyed. Just when Mr. Chen Zihe went back to his hometown to visit relatives, he found that the folks often drink wild vine tea on the top of the stone buddha. Not only are they rarely sick, but they are full of energy and cheeks are rosy. After Chen tastes this tea, the taste is comfortable, it is a good idea. Beijing time brought a package to the Emperor Guangxu for drinking. Guangxu tastes it, feels different flavor, refreshing taste, comfortable throat, so it is often used for tea. In less than half a year, Guangxu not only disappears from the dark spots and acne on the face, but also feels refreshed and strong. To this end, the Emperor Guangxu will seal the "Tianzi Tengcha" to the vine tea. Since then, the vine tea has been widely circulated in the folk, and it has also spread overseas. It still enjoys a high reputation among the countries of Nanyang and Southeast Asia. The second is the exchange of Jinshi tea. In a Qingming Festival a long time ago, a scholar who went to Beijing to pass the exam passes through the Pingcun Village in Pingshan Township, Shiqian County. The time is like a layer of thin veil flowing. In the fields of the mountains, the dense tea trees under the mist support the waist, rushing to spit Xinnai, and sprouting green sprouts, emitting a faint orchid, the beautiful environment here is deeply attracted. This talented person. Then he ordered the follow-up ceremony to stay in the village to enjoy the scenery. When you walk into the farmhouse, people treat each other with tea, the smell of tea is fragrant, and the scorn of the product is refreshing, refreshing and refreshing. When I was on the road, I brought a few baskets of tea and used it along the way. One line went to the capital, I saw the hearts of the inside and outside of the court, and the inside and outside of the city gate were full of obituaries. It was originally because the Queen Mother was sick and difficult to heal. The court told the world to ask for medicine, and the readers saw this, and described the wonderful effect of Pingtan tea. Fan, and then presented to the palace. In a few days, the Queen Mother was cured, and the Emperor was given a testimony to the scholars. Since then, Shiji County Pingkan Tea has also gained a lot of fame. The third is the treatment of moss tea. In the past, there was a cave in the mountains of Xinhua in Wude Town. There are two masters of spiritual practice in the cave. If the villagers lack food and clothing, they can go to the cave for help. If there is disaster, drink the water of the cave. Can also eliminate the disease. Therefore, the surrounding villagers came here to pray for peace and happiness. One day, an old man suddenly broke into a disease, and his family helped the cave to seek treatment. At this point, the water source dried up, the leaves in the pool were deposited, and the old man could drink without water. In the rush, the leaves in the pool were chewed and swallowed. The sweetness is sweet, the taste is very good, the liquid is in the stomach, the feeling is refreshing, and the pain is completely removed, so the seeds on the deciduous trees are taken and planted. The news spread, people went to the cave to pick the net pool and planted trees. In a few years, the tree was covered with mountains and trees. This tree was called "the moss tea tree" by the locals.
