Historical and cultural Lu Yi was called "Ming Road", "Bitter Water", "True Source", "Guyang" and "Fairy Source" in ancient times, and it was changed to Luyi County in the second year of Yuan Dynasty (1265), and the county name is still in use today. Laozi, a great philosopher, thinker, founder of Taoist school in China during the Spring and Autumn Period and one of the world's top historical and cultural figures, and Chen Tuan, a famous scholar and Taoist in the early Song Dynasty, were born here. The Tao Te Ching written by Laozi is recognized as the oldest philosophical classic in the world, and its circulation is the largest except the Bible. Taiqing Palace, Laojuntai and other cultural relics commemorating Laozi are well preserved. 200 1 Laojuntai and Taiqing Palace sites were approved by National Cultural Heritage Administration as national cultural relics protection units. Lu Yi presided over the "Lao Zi Stamp Launching Ceremony", held the "Lao Zi Academic Seminar", organized the excavation of the hidden mountain cultural site, built the Lao Zi Memorial Tower, and started the tourism development of Lao Zi's hometown, which laid a good foundation for the development of tourism in Lu Yi. There are many places of interest about Laozi in Luyi County. Taiqing Palace is the most important memorial building left by Laozi's birthplace. At present, there are pond hall, three Tang Songbai trees and more than a dozen ancient inscriptions. Among them, "The Inscription on the Tao Te Ching by Emperor SHEN WOO in Kaiyuan of Tang Dynasty" is an interpretation of the Tao Te Ching by Xuanzong, and it is a treasure among cultural relics. The palace, located one mile north of Taiqing Palace, is a building group in memory of Li's mother. It includes the main hall of the Zhou Dynasty and some temples, where the monument of Song Zhenzong's "Imperial Book Seal" is located. Laojuntai in Luyi County is a part of Mingdao Palace Courtyard in Tang Dynasty. When I was young, I taught here. Laojuntai is also the legendary place where I became an immortal. Therefore, it is also known as Denggao Sendai, which is tens of feet high and has a dense forest of Cooper, which lasts for thousands of years without being destroyed. In addition, there are many places of interest in Luyi County, such as Yinyang Mountain, Laixianggou, the memorial archway of "ancestor of all religions", the address of Confucius, Jiulong Well, Wangyuejing, Wupingcheng and Chen Tuan Temple. Taiqing Palace was built in the Eastern Han Dynasty, formerly known as Laozi Temple. In the Tang Dynasty, it was renamed Taiqing Palace, which was the place where Laozi was sacrificed in previous dynasties. After the establishment of Taoism, Laozi was honored as the founder, and Taiqing Palace became the ancestral home of Taoism and a sacred place in the minds of Taoists. Li Yuan, the founding father of the Tang Dynasty, respected Laozi as his ancestor, and Taiqing Palace became the royal temple of the Tang Dynasty, which was greatly expanded. According to ancient records, the Taiqing Palace in the Tang Dynasty was as grand as Chang 'an Palace. At this time, Lao Tzu's position is really the best in the world. In the birthplace of Laozi, Emperor Xuanzong of Tang Dynasty set up a "Tang Kaiyuan SHEN WOO Daodejing Annotation Monument", which is one of the earliest and most valuable inscriptions in the history of Laozi's birthplace. Dong Xiao Palace, commonly known as the harem, was originally named Li Mu Temple. In the Tang Dynasty, it was changed to the Temple of the Congenital Empress Dowager, and later renamed Dong Xiao Palace, which was the place where Li Mu was worshipped in previous dynasties. Zhao Henglai, from Song Zhenzong, made a memorial for the Queen's imperial brush calligraphy and set up the "Three Imperial Monuments", which is a praise for the Queen Mother. It is located in the southeast of Dong Xiao Palace. It has been built for thousands of years, but it is still intact. According to experts, it is one of the four Song Dynasty monuments preserved in China at present. In addition, there are more than 10 inscriptions of the Jin, Yuan, Ming and Qing Dynasties. During the period of 1997, archaeologists excavated a large-scale cultural relic group in Taiqing Palace, including Longshan cultural site, Western Zhou tombs, Eastern Zhou rammed earth foundation site, large Ma keng, Tang and Song architectural foundation sites, inscriptions and Ming and Qing buildings. The site has an early age, a large span, well-preserved, rich cultural connotation and high historical, scientific and artistic value.

Subsequently, more than 60 well-known archaeologists and experts on old things from Peking University, National Cultural Heritage Administration, China Academy of Social Sciences, Institute of History and the whole country gathered to study the results of this excavation, and agreed that a large number of sacrificial utensils found proved that the Taiqing Palace offered sacrifices to the elderly and the harem offered sacrifices to Li's mother, which was completely consistent with the literature records of previous dynasties.
