Longjing, also known as Longjing Tea, is a type of green tea and one of China's most famous and widely produced tea varieties. Longjing Tea is named after the Longjing well. Longjing is located northwest of Wengjiashan Hill, west of West Lake, in what is now Longjing Village. Originally named Longhong, it is a circular spring pond that never dries up even during severe droughts. Ancient people believed this spring connected to the sea and housed a dragon, hence the name Longjing. Legend has it that Ge Hong of the Jin Dynasty once practiced alchemy here. About 500 meters from Longjing, in Luohuiwu, stands Longjing Temple, commonly known as Old Longjing, built in the second year of Qianyou during the Later Han Dynasty (949 AD). It was initially named Baoguo Kanjing Temple. During the Northern Song Dynasty, it was renamed Shousheng Temple. In the Southern Song Dynasty, it was again renamed Guangfu Temple and Yan'en Yanqing Temple. It was not until the third year of the Ming Dynasty's Zhengtong era (1438 AD) that it was moved to the side of the well. The temple is now abandoned and repurposed as a tea house.

Longjing is one of the four famous springs in Hangzhou, known for its clear, sweet, and excellent water quality. The water in Longjing Spring consists of two parts: groundwater and surface water. Groundwater has a higher density, so it lies beneath the surface water. If you stir the spring water in the well with a stick, the groundwater below will rise to the surface, forming a distinct water division line. As the groundwater gradually sinks back down, the division line shrinks and eventually disappears, which is quite fascinating.

Longjing Tea is celebrated worldwide and is categorized by origin into Shi (Lion), Long (Dragon), Yun (Cloud), and Hu (Tiger), referring to Shifeng, Longjing, Yunqi, and Hupao areas. After the Republic of China era, Meijiawu's production increased significantly. Previously, people ranked the quality of Longjing Tea based on the five production areas: Shi, Long, Yun, Hu, and Mei. After the liberation, Longjing Tea began to be widely cultivated throughout Zhejiang Province, leading to varying quality. It is now uniformly classified into West Lake Longjing, Qiantang Longjing, and Yuezhou Longjing, with West Lake Longjing being the highest quality.
