Going to the tea plantation is a traditional folk custom in Yushan, Pan'an County, Zhejiang Province. The Yushan Ancient Tea Plantation is located in Matang Village, Yushan Town, Pan'an County. It was first built in the Song Dynasty and rebuilt during the Qianlong period of the Qing Dynasty. It is the earliest ancient tea trading site found in the country. When Xu Xun of the Jin Dynasty traveled to Yushan, he made great contributions to the development of local tea production and the opening of tea sales. The people of Yushan felt grateful for his kindness and respected him as the "Tea God". They built temples and statues and worshiped him all year round. In the Song Dynasty, a temple was rebuilt for the Tea God, and a tea plantation was opened on the side. The temple was therefore called the "Tea Plantation Temple", and two seasonal temple fairs, "Spring Society" and "Autumn Society", centered on tea trading, were formed. The "Spring Society" is scheduled on the fifteenth day of the first lunar month. At that time, local tea farmers will come to the tea plantation in their best clothes to hold folk cultural activities such as community drama performances, hanging lanterns, and welcoming dragon lanterns (pavilion lanterns). The "Autumn Festival" is held on the 15th day of the 10th lunar month. Tea farmers and common people carry tea and goods from all directions to the tea plantation to attend the market, forming a lively and grand temple fair. In addition to the trading of goods, there are also various folk art performances during the "Autumn Festival", such as the Thirty-Six Lines, Stacking Arhats, Lifting the Eight Immortals, etc. In the tea plantation temple fair, the trade of tea and medicinal materials is closely linked to agricultural production, which promotes the development of local production, economic prosperity and social harmony. The tea plantation has a complete set of grand tea god memorial ceremonies and a series of colorful folk art activities, which are widely participated by the masses and have been passed down for a long time, from ancient times to the present. Protecting and inheriting this folk cultural activity is of extremely important practical significance for the maintenance of the ancient tea plantation and the development of local tea production.
