Located in Miaoxi Town, southwest of Huzhou City, Zhushan Mountain was named after Emperor Zhu of the Xia Dynasty hunting expedition to the area. During the Jin Dynasty, it became a famous scenic spot in Wuxing County. Zhushan Mountain is also known as Baoji Mountain, named after Baoji Temple in the south of the mountain. Baoji was the name of Miaoxi Temple during the Liang Dynasty, where the abbot was Jiao Ran (also known as Qing Zhou, a native of Changxing County). In the 7th year of the Tang Dynasty’s Dali period (772), the famous calligrapher Yan Zhenqing served as the governor of Huzhou. Yan was a friend of Lu Yu and Jiao Ran and he highly respected Lu Yu. Therefore, the three friends, and others often gathered at Zhushan Mountain. Yan Zhenqing even invited Lu Yu to work on the compilation of  “The Ocean of Rhymes and the Mirror of Sources”. On October 21st in the 8th year of the Dali period (773), Yan Zhenqing specially built the “Sankui Pavilion” for Lu Yu. The pavilion was named after the year, month, and day of its construction, which was in the year of Kuichou, the month Kuimao, and on the day of Kuihai.

Lu Yu lived in Huzhou for more than thirty years, and Huzhou became his second hometown. During this time, Lu Yu traveled to areas such as eastern Zhejiang, southern Jiangsu, and northeastern Jiangxi to participate in tea-related activities. However, his main focus was on tea research and the writing of “The Classic of Tea” in Huzhou. In Huzhou, Lu Yu spent 30 years writing the world’s first tea research monograph, “The Classic of Tea” which comprehensively discusses the characteristics, functions, quality, origin, water quality, picking and processing, and brewing methods of tea. Although the entire book consists of 3 volumes and 7 chapters and only contains 7,000 words, it went through three revisions and finally became a masterpiece that has been passed down through the ages. Lu Yu passed away in Huzhou in the 20th year of the Tang Dynasty’s Zhenyuan period (AD 804) and was buried in Zhushan Mountain at the age of seventy-one. His achievements in the field of tea have been widely recognized in the world and he is known as the “Tea Sage” by later generations.
